Kartoshka cakeCocoa and cake crumb truffles
Soviet cafés and school canteens sold these knobbly brown 'potatoes' for a few kopecks, and they began as a thrifty way to use up sponge and biscuit trimmings at the bakery. Crumbs are bound with butter and sweetened condensed milk, flavoured with cocoa and vanilla, shaped into little potatoes, rolled in cocoa and finished with two dabs of pale butter cream for the sprouts. They are fudgy and dense like a brownie truffle, need no oven, and children love making them. Traditional bakers added a spoonful of rum, an optional extra for adult batches only; this version is alcohol-free with vanilla. The usual slip is coarse crumbs, which make the potatoes crack, so blitz them as fine as sand. Chef's tip: chill the shaped potatoes for at least 20 minutes so they hold their shape and slice cleanly.
