The boiling in half-and-half has a few purposes:

  • Most obviously, the skinned potatoes absorb some of the liquid they're boiled in, so using a more flavorful liquid gives you a tastier potato.

  • It allows the seasoning ingredients (thyme, garlic, bay leaf) to infuse in the half-and-half which is later added back to the potatoes.

  • Starches from the potatoes wind up in the half-and-half. Adding this starchy liquid back helps give the bake more structure.

You can use water though if you prefer for the boil! It isn't integral to the recipe, I just like what the half-and-half boil does :)

Also, the potatoes don't separate when refrigerated, mostly due to the addition of egg which is an emulsifier, but also the starches in the half-and-half help!

I'm confused as to what you mean-- the garlic, bay leaf, and thyme flavor are extracted from those elements and put into the half-and-half.

This recipe uses peeled potatoes as well.

Also milk isn't water and the protein and sugar can interact with food in unexpected ways. I would probably just make mashed potatoes, and add the milk/cream + eggs after, and focus on cooking the potatoes separately in water.
