I reserved a copy of David Lebovitz's Perfect Scoop at the library a while ago. I just picked it up the other day. I need to buy it. The breadth of recipes is fantastic. The recipes themselves seem well-designed, too.
The book actually has a recipe for chocolate peanut butter ice cream. This is something that I've been fooling around with for some time. The book's recipe is simplicity defined. Pour a pint of half-and-half into a pot, add some sugar and cocoa powder. Heat and stir. Remove from heat. Add peanut butter. Chill. Pour into machine.
The texture is smooth and coats your mouth in a pleasant way with the two flavors. The overall flavor does lean just a little towards the PB side but that's good. If I want to change it in the future, I'd probably add just a little more cocoa powder.
My adventures with making ice cream. And eating it, too.
