I took it to a large group meeting and quite a few people tried it out...
The people who truly LOVE peanut butter felt it was lacking something.
The folks that just wanted a rush of peanut butter on a cracker or bread were perfectly happy with it.
Some folks didn't like seeing it after an hour or so because it dries out if you don't cover it.
The chemist in the group was a tad freaked out because one of her projects at the university was to work with a company to remove the fat from peanuts! To do this she ground them up, added fomaldehyde, which binded with the fat molecules, then burned that off, leaving behind the solid protein peanut.
She wouldn't touch it and the rest of us all just stared at the jar after that.
I have no idea what process this company uses to remove so much of the fat. But chezz, I'd be happy to pop some in the mail for you to test if you like. I forget the ratio, but you simply mix water with the powdered peanuts.
I tried it in two recipes, but think I made too many other adjustments (fat-wise, flour-wise). Neither were rousing successes.
However, it was really good in an almond milk, yogurt, banana smoothie.
Offer goes to anyone who wants a sample. Just PM me. I'll be on medical leave starting this Thursday, so I could mail it out next week.
