Soon as I find the recipes I'll have an excuse to get them synced to a cloud cookbook and just have them.
I know it's milk, sugar, peanut butter and vanilla (I highly recommend the real stuff but it is costly) and probably butter (again, real thing, never skimp on it or cut it out, damn the blasphemous anti-butter heathens!), but I don't remember how much of each.
And unless you have a very good candy thermometer it's best to not use one and instead to a bit of the sugary liquid in ice water (and even then many people don't use one at all). Other than that a big pot, metal spoon, amd a tray to pour in it (I use a cookie sheet) is all you really need to make it.
And reading this thread, while I'm pretty hungry, had me thinking of peanut butter stuff to make. I even had the idea for a peanut butter gravy and going over what spices and peppers would be good in it and what kind of dishes it would be good in. I'm thinking it might be a very wild twist with fried chicken and mashed potatoes, biscuits and sausage gravy, and a pot roast.
Or some peanut butter sauce on a heap of rice, peppers and some lightly fried chicken. Or may just boil some noodles with a blend of spices and mix that in the sauce?
Maybe pancakes with melted peanut butter added to the batter?
There are recipes for peanut butter smoothies and shakes.
Mostly I just smear it on bread and put it on crackers. I like peanut butter (love it when it's fresh ground with just peanuts), but it's not something I've cooked with much.
I suppose you probably can, to a degree, substitute oil in recipes with peanut butter (much like how you can replace the eggs and oil in a cake with Miracle Whip), so that might be a starting place to open up some doors working in to more recipes.
