A week or so back, on a trip to a grocery store called WinCo, I found something called "instant refried beans." As in, just add water and cook it, and you have refried beans. I decided to try it, because I like refried beans, but I use them so infrequently that I often will open a can, use half of it, and the other half goes bad in the fridge waiting for me to use it. This way, I could make only as much as I would need.
Well, I finally got around to trying it, and it lives up to its promise. I think I'll have to cook it a little less, stir it more, but it's pretty good. And seeing as the powder takes a hell of a lot longer to go bad (like most powdered foods), it's perfect for me. I think I will be getting it again.
