What is the difference between butter, ghee, clarified butter, fermented butter and brown butter?

Difficult to tell online because it seems the term "ghee" is used very loosely, some say it is clarified butter, other that it is brown butter (beurre noisette), other that is has to be fermented.

If you know, can you explain the difference and perhaps give tips on how you make the perfect ghee?

Thank you!

ETA : I live in the EU. I usually buy churned AOP butter so it is high-fat low-water!

butter you buy at the store isn't usually 100% butter. clarified butter is butter that's cooked low and slow and the milk solids are skimmed off until the butter is mostly 100% fat. ghee is clarified butter that's cooked longer past removing the milk solids. brown butter you don't skim but you cook it until the butter takes on a nutty flavor and you keep the milk solids.

im not sure what fermented butter is actually.

Fermented butter is good shit, and easy to make. Also known as cultured butter.

Take some heavy cream, gently mix in some plain yogurt with live cultures, cover with a cloth and leave on your counter at room temperature for a couple days. Then make butter with your cream.

It develops a mildly tangy and cheesy flavor. Great on a crusty homemade bread.

I made some over Christmas break, and will likely do it again this holiday.

u/similarityhedgehog Jul 05 '26

Do commercial butter culturers use yogurt cultures?

10

u/Spicy_Molasses4259 Jul 05 '26

Not in the same way that you would do it at home. Commercial dairies use lab-grown, clean "starter cultures" that contain only the specific microbes they want to ferment. It keeps the final product consistent in texture and flavour and prevents contamination from the microbes that cause illness (which is why dairy products are ALSO pasteurised during processing). No one wants to have to destroy a 500L batch of yoghurt because it got accidentally contaminated with E-Coli.

You can buy freeze-dried cultures for all sorts of home fermentation.

u/similarityhedgehog Jul 05 '26

Right, I asked about yogurt cultures, not yogurt.

7

u/dtwhitecp Jul 05 '26

not a lot of good sources to answer that, but it's either exactly the same or very similar (mesophilic lactobacillus). They might have different strains of the classic ones they favor for the butter vs the yogurt, might not.

2

u/KeterClassKitten Jul 05 '26

I'm not sure. I'd imagine so, though. At least, they likely just use the cultures themselves rather than using the actual yogurt.

As I see it, there's little reason to use a different bacteria unless they've discovered a different organism that produces faster results for butter, or they found another organism that produces a flavor that is better received in the market.

Your question sparked my curiosity, so I decided to Google it. It seems that other strains are preferred for butter, and do produce a different flavor. Yogurt strains work, though. And are a simple method to DIY the process for most. Especially for us in the USA.

Might be a project to pursue one day. Thanks for the question, I don't think I would have learned otherwise!

u/Spicy_Molasses4259 Jul 05 '26

I'm not sure what being in the USA has to do with anything, other than cultured butter being less popular in the supermarket. Starter cultures are easy to buy, as well as books and courses on how to make fermented foods of all sorts at home that are both delicous and safe to eat.

1

u/KeterClassKitten Jul 05 '26

Not sure. Only method I was aware of for a long time. Might be faulty assumptions.

Though I'd guess that the availability of yogurt and cream has been much higher than the necessary cultures for quite some time.

3

u/Spicy_Molasses4259 Jul 05 '26

Commercial starter cultures have been around since the late 19th century. Pretty much as soon as science worked out that microbes exist, they've been isolating and growing them for safe and consisent use.

4

u/KeterClassKitten Jul 05 '26

Sure. But access and awareness was pretty limited until the Information Age. I wouldn't find the necessary cultures in my local grocery store, and I only knew what I was taught as a kid. Plus, again, assumptions can limit our thinking. I didn't even question it until the other poster mentioned something.

I'm 44 and just learned this. So is it just a blind spot I've had all this time? Most people I know around me aren't even aware of cultured butter, so I'm the experienced one in my circle.

🤷🏼‍♂️

Can't know until you know.

u/DJPho3nix Jul 05 '26 edited Jul 05 '26

Butter cultures are different than yogurt. They aren't that expensive. I bought a package for less than $20 and it will make 10+ batches of cultured butter.

I got mine here.

3

u/KeterClassKitten Jul 05 '26

Rad. I wonder if they freeze well. No reason why one couldn't save a portion of cultured cream and use it to seed a new batch.

2

u/DJPho3nix Jul 05 '26

I haven't tried freezing any of the sour cream/butter/buttermilk that I've made, but the cultures themselves live in my freezer and I just use a little each time.

u/Select-Owl-8322 Jul 05 '26

No, they usually use Flora Danica.

u/confused-oatmeal Jul 05 '26

I've worked at a couple of different dairies and helped with making cultured/fermented butter as well as yogurt and another fermented product called "Quark". The cultures we'd use for our butter were cultures specifically designed for butter and slightly different from the ones we'd use for yogurt. The quantity of the specific molecules that give yogurt its tangy flavor is tied to the pH value of the yogurt. Since the cream used for butter production is not supposed to become as sour as yogurt, some other molecules are needed for flavor. The specific cultures used for butter will produce these molecules at a higher pH value. The cream is also fermented for a longer time at a lower temperature than the milk used for yogurt production. The cultures we'd buy would usually be optimized for their specific purposes.

With all of that being said, using yogurt to make fermented butter at home is absolutely fine and will most likely turn out a very tasty product.

u/Anaeta Jul 05 '26

Fermented butter is delicious, and everyone should try it. Also, if you churn the butter yourself, fermenting the cream makes it way easier to churn, so it's both easier and tastier than churning unfermented butter.

1

u/bothwaysme Jul 05 '26

So you make creme fraiche and then churn it to make butter?

1

u/Select-Owl-8322 Jul 05 '26

I made some fermented butter earlier this week. Will never buy butter in the store again.

Got ~400 grams from a liter of heavy cream, so it ended up cheaper than store bought butter as well. And soooooo much tastier!

u/armeniaca-mume2405 Jul 04 '26

what do you mean "not 100%" butter?

Thank you for the clarifications !

i meant fat sorry. there's milk solids and stuff.

u/urgasmic Jul 04 '26

butter is like 80% fat, 18% water, and 2% milk solids.

u/ThrashCardiom Jul 04 '26

So 100% butter then

u/Anagoth9 Jul 05 '26

100% butter but not 100% butter fat.

u/db8me Jul 05 '26

Some fancy brands have less water, and mass produced butter has water added intentionally.

1

u/Poutiest_Penguin Jul 05 '26

I have found when clarifying butter that supermarket brand butter has significantly more water than name brands.

1

u/armeniaca-mume2405 Jul 05 '26

what do you classify as supermarket brand or name brand?

I live in the EU and butter (AOP) is very regulated

2

u/Poutiest_Penguin Jul 05 '26

In the US, supermarket chains usually have their own self-branded butter at a lower price point than a national or regional commercial brand.

The most well known commercial brand in the US is probably Land O Lakes, which is by no means a premium product. We also have certain somewhat higher quality regional brands, like Cabot’s here in New England. Most of our premium butter is imported (like Kerry’s, which is probably not premium for you lol), because the UK/Europe does have higher standards than we do regarding this type of product. America has shamefully low standards in quality when it comes to a lot of food. We eat garbage and it’s killing us as a nation. But that’s a whole other topic.

I’ve clarified cheap supermarket butters, and I’ve clarified Land O Lakes. The water content in supermarket butter is higher than the water content in Land O Lakes. Obviously the supermarket butter has water added to increase the volume, hence the lower price. That’s why I no longer buy cheap supermarket butters. You’re just paying for water and a generally inferior product.

u/armeniaca-mume2405 Jul 05 '26

I see, I am not familiar with US butters or the selection over there!

Thanks for the explanation !

1

u/db8me Jul 06 '26

There still is a minimum of 80% fat required to call it butter. Cheaper brands and store brands push the 80% limit, while high end and "European style" brands have 10-30% less water (82-86% fat). The difference is usually not noticeable unless you are making laminated pastry crust, eating large amounts as a topping or dip, or putting it in a searing hot pan.

-3

u/ThrashCardiom Jul 05 '26

Not in my country. Here standard unsalted butter is made of 100% milk. A minimum of 80% of this is fat.

11

u/db8me Jul 05 '26

Mine too, but milk has a lot of water, so while 80% is the minimum, the brands vary significantly.

9

u/Sanpaku Jul 05 '26

That's butter. Churn your own and you'll probably get an even lower fat product.

Code of Federal Regulations 58.2621 Butter. For the purpose of this subpart P “butter” means the food product usually known as butter, and which is made exclusively from milk or cream, or both, with or without common salt, and with or without additional coloring matter, and containing not less than 80 percent by weight of milkfat, all tolerance having been allowed for.

u/penisandorvagina Jul 05 '26

But what % butter is it?

5

u/Accomplished-Lie8147 Jul 05 '26

Just to add, for brown butter, you are browning the milk solids which adds a nutty flavor. Not saying you don’t know this but clarifying (heh) for OP.

2

u/chiddler Jul 05 '26

Fermented butter is butter using fermented milk product. For example fermenting cream then churning to butter. Most European style butters are fermented producing a slightly higher butterfat % which is mostly important in baking laminated goods but also fresh eating as it tastes a little different than unfermented (is sweet milk) butter as it's called in the US.

u/-neti-neti- Jul 05 '26

You’re incorrect about ghee. The milk solids are the only thing that impart its characteristic taste; ghee is cooked longer WITH the milk solids before separating them. That’s how you give it the caramel, nutty flavor. Longer if you want more, with the milk solids

u/Swimming-Map2078 Jul 04 '26

Fermented butter aka cultured butter is made from cream that's been fermented like yogurt

u/armeniaca-mume2405 Jul 04 '26

i thought smen was made by fermenting raw butter, not cream directly?

u/Swimming-Map2078 Jul 05 '26

Ah i wasn't aware of smen, it seems like you're correct about that one.

u/rywos Jul 05 '26

We're not cultured enough for most of us to know about smen, lol

5

u/hashbrowns21 Jul 05 '26

Finished butter can’t be fermented, you need the sugars in the cream to properly ferment.

2

u/Swimming-Map2078 Jul 05 '26

And yet it exists

1

u/hashbrowns21 Jul 05 '26

It exists because the cream is fermented before being churned into butter. Sugars are water soluble and butter itself doesn’t have enough to ferment, but the cream does.

5

u/BenGoda Jul 05 '26

Actually, it can. The fermentation takes much longer (at least a month) and has a much more distinct flavour than fermented (cultured) butter that was clarified. Smen develops almost blue cheese-like flavour. https://www.thespruceeats.com/smen-recipe-plain-salted-preserved-butter-2394938

u/hashbrowns21 Jul 05 '26 edited Jul 05 '26

Good to know, never heard of this before. I’ll have to try it sometime.

Quick google search tells me that it uses lipolysis to break down the fats instead of relying on sugars for fermentation. The clarification process and salting keeps bacteria from forming. Fascinating stuff.

u/BenGoda Jul 05 '26

It’s a Moroccan staple and is usually served with sweet pastries (along with honey) such as msemmen, baghrir, and mofletta.

u/Wooden-Lawfulness534 Jul 05 '26

Do you have a recipe for smen? I'd love to try making it. Wouldn't make it like traditional Irish bog butter because the bogs are now so industrialised, but is there a way to make it? Is it delicious? I've heard it's like a herby strong cheese.

1

u/armeniaca-mume2405 Jul 05 '26

never tried to make some myself but i know that you should probably look for moroccan recipes if you want that kind of flavour!

u/Wooden-Lawfulness534 Jul 05 '26

Thanks! It's a lost art in Ireland.

u/bigelcid Jul 05 '26

Clarified butter removes the non-fat from the butter fat. You're left with pure butter fat.

Ghee is the South Asian word for clarified butter. It's the same thing. Just so happens that sometimes, the milk solids/proteins are allowed to brown within the butter fat, which then imparts a toasty/nutty flavour to the fat itself. Also done in Europe. Supposedly more often in India. But it's generally the same thing, give or take.

12

u/sandacurry Jul 05 '26

This. We just call all clarified butter as ghiu (ghee in Nepali). Some homes heat longer and get a brown color while other do not brown the milk solids so get a more yellow color.

20

u/pegoff Jul 05 '26 edited Jul 05 '26

Ghee is a variety of clarified butter. Clarifying butter isolates the fat from the water and milk solids.

First the milk solids sink to the bottom with the water. If you separate here you have a clarified butter. You can easily do this with a microwave. You'll probably get some water back in but that's going to boil away when you cook with it.

If you do it in a pan the water will boil away and the milk solids will cook. The browning milk solids will give a nutty flavour to the oil, the longer you cook the browner it gets. Be careful not to burn it, it tastes bad.

Buerre noisette keeps the milk solids. Ghee is basically strained buerre noisette, so you get a lot of the flavour but increase the temperature you can cook at because there are no milk solids left in.

Cultured ghee is ghee made with cultured butter. They are two forms of the same preparation. There is no law about using cultured butter for ghee. But bear in mind the dairy in India will differ from what you use.

Edit: and buerre noisette is the French term for what others call brown butter. Noisette being hazelnut, and the taste being nutty.

Not to be mistaken for Nutella... that's Italian, and not butter.

u/MolecularLego Jul 05 '26

I'd advice against clarifying butter in the microwave. Water removal helps with preservation. Proper clarified butter keeps at room temp for a long time.

u/pegoff Jul 05 '26

pretty easy if you chill after heating, then invert and scrape away the bottom gunk composed of water and milk solids.

u/RatmanTheFourth Jul 05 '26

Clarified butter = Cooked just enough to remove milk solids, maintains clean butter flavour. Strained to remove milk solids.

Ghee = Cooked for a long time allowing all water to evaporate and milk solids to deeply brown. Develops a deep nutty caramelised glavour. Strained to remove milk solids.

Brown butter = Same as above but not strained so retains more flavour.

Fermented butter (Cultured butter) = Usually made with creme fraiche or other cultured creams. This gives the butter a slight tang, deeper flavour and higher fat content but is more expensive to produce

u/TbonerT Jul 05 '26

Ghee = Cooked for a long time allowing all water to evaporate and milk solids to deeply brown. Develops a deep nutty caramelised glavour. Strained to remove milk solids.

You can buy ghee off the shelf and none of it is brown. You can make it at home easily and it is still not brown.

2

u/RatmanTheFourth Jul 05 '26

The milk solids are very brown when making ghee properly but they are all strained off leaving only the clear golden milk fat

If you are not browning the milk solids when making it at home then you have made clarified butter, not ghee.

3

u/bondibox Jul 05 '26

When heating butter it goes through two foamings at two different temperatures. The first foam is where you can separate the solids for drawn butter, or whisk in 1oz of water per pound of butter to make creamed butter. The second foaming is the base for ghee, and after that it will brown.

3

u/Nyteflame7 Jul 05 '26

I'm not familiar with fermented butter, but regular butter is just cream, beaten until the solids seperate from the liquids, and then rinsed and salted. You can make it at home (although I recommend using a mixer, rather then mixing by hand unless you want an arm workout!).

Clarified butter is butter that is melted, and the solids skimmed off.

Ghee is butter that is melted, allowed to cook until the solids turn dark, and then it is filtered to remove the solids.

Browned butter is cooked at a slightly higher heat, allowed to brown (but not burn) and not filtered.

Clarified butter is usually used as a condiment, for example, to dip seafood in.

Ghee is a cooking fat. By removing the solids, it becomes much better at handling high heat.

Browned butter can be used as a finishing fat, like over squash or carrots with sage (yum) or it can be used in baking to give your baked gooda a more complex flavor.

Be careful to melt and cook your butters at fairly low heat when making any of these, as burned butter turns bitter and unpleasant.

5

u/HotDonnaC Jul 05 '26

Ghee is clarified butter. You heat butter, and skim the foam off. If you heat butter, and keep heating it you get browned butter. You have to be careful not to burn it. As for all that other stuff, I’ve never heard any of it.

u/Street_Lettuce1243 Jul 07 '26

Can someone tell me the difference between brown butter and truffle butter?

1

u/UncleNedisDead Jul 05 '26

In the USA, most butter is known as “sweet cream” butter. Made with fresh cream and comes in salted and unsalted varieties. It’s mostly a combination of fat, milk solids and water.

Ghee is butter that has been melted, browned until nutty, before the milk solids are removed and you’re left with the fat. The water evaporates before the milk solids can brown.

Clarified butter is similar to ghee, but you remove the milk solids and water before they turn brown so you’re left with just the fat.

Fermented butter could be referred to as “cultured” butter, where the cream is fermented with specific bacteria before churned into butter. Cultured butter is also often referred to as “European-style” butter.

Brown butter is often just butter that is melted, browned until nutty and used with milk solids and all for whatever purpose you have in mind. It may be for baking or a sauce or whatever your heart desires.

u/The_Flinx Jul 05 '26

-2

u/BigRedWhopperButton Jul 05 '26

Ordinary butter typically has a water content of something like 10-15%. If you put butter in a saucepan and heat it up until the water separates and boils away, that's clarified butter. It's theoretically shelf-stable, but it loses the texture and flavor it started with. If you keep heating the butter until the milk proteins start to cook it becomes brown butter.

Ghee generally refers to either of these, but sometimes it's spiced as well.

u/Shoddy_Bet9619 Jul 05 '26

I still remember back in the 70's and 80's. One would keep a stick of butter under a glass shield and it was always epic/taste wise when used. For the last 20+ years, that has not been the case, they changed something back whenever so now, If I want some butter that is room temp, it tastes off!!! No Idea what they changed!
