It was this funky recipe by B. Dylan Hollis, a "pinto bean cake." (Watch the video, it's only like a minute and he's funny)
It went horribly, from the get-go. For one, I discovered that a magic bullet is no substitute for an actual food processor. My first attempt at grinding half a cup of peanuts into powder resulted in a concoction of half peanut butter half whole peanuts. My second attempt, doing it in smaller amounts in a pulsing pattern, resulted in mostly powderized peanuts but still with some whole peanuts in. I didn't press my luck, as I was now Out of peanuts.
I then discovered the honey I'd be using - "all-natrual" at my mother's insistence, was more honeycomb than honey, and it was a total pain in the ass to get into the mixing bowl.
Finally, I made the poor choice to choose Convection Bake on our oven instead of just Bake. Convection Bake seemed to decide that 352° with a fan on was just as good as 375° with no fan. So after checking on the cake at the allotted 45 minutes, I found a jiggly pile of unbaked goop with a crust on top.
After switching to regular bake, and leaving it in until the top started to burn, I had to give in and take it out even though it was still failing the toothpick test. It's cooling on the counter right now. I bought a brand new strainer and 9-inch springform cake pan for this. If this recipe fails tonight, you bet your goddamn ass I'm going up to the store again tomorrow to buy a Food Processor, more beans, more peanuts, plain ol' filtered honey, and I'm gonna try this again until I get it the fuck right, because I am nothing if not a stubborn motherfucker.
Will update later with pics.
