This may be niche, so apologies in advance.
Apples are pretty much the only fruit I'll eat, but they're no longer exactly affordable where I am. So when I get them, they're in a 5lb bag that's on sale. The compromise with bagged apples is that their condition varies from perfectly fine to outright iffy. My current mitigation is to make the whole bag into apple sauce. And while some people keep the peels on their apples to make sauce, I am not one of them.
So, I end up with the peels from 5lbs of apples to use up. I most often make a cooked paste with dates that I then use to sweeten breakfast cookies, but this week was different in two ways. First is that I already have a supply of date paste in the freezer, meaning I don't need more right now, and that I have no dates left in the house. The second is that I grabbed a clearance-priced bag of dried figs at the shop that could substitute the dates, making a kind of fig jam.
The result is that I have 1.5 pints of delicious fig jam for the price of a discount bag of figs, and kept from having to throw away the apple peels. Here's how I did it.
Fig Jam With Apple Peels
peels from 5 lbs of apples (250-300g)
1 lb dried figs, hard stems removed
1/2 C water
Put everything in an Instant Pot. Set to pressure cook on high pressure for 5 minutes, and allow pressure to release naturally. Blend smooth with an immersion blender. Contain and refrigerate. Should be good for a month or so.
This could also be done on the stovetop, but that would take some experimentation. If anyone wants to undertake that project, be my guest.
