I experienced a (minor) flood of interest in my offhand reference to “ketchup pistachio cake” in the post just below. Are you pulling our legs, Joe? Actually no, though I’ve never actually seen a recipe for it, just a picture in a book called The Gallery of Regrettable Food by James Lileks. It looks to me like a combination of Heinz ketchup cake (oh yes, that still exists and it looks eerily like this week’s project, no?) and a green-tinted pistachio frosting (almost certainly something like this right here, made with instant pudding mix and Cool Whip). Ye who may be interested, knock yourselves out. I’ll look the other way.
