My husband, The Hungry One, is a man with clear tastes and preferences. He likes chocolate. He loves coffee – perhaps a little too much. But curiously, top of all things, he values texture in his food. And when it comes to a cookie, it’s the chew which is key. These choc-hazelnut biscuits are the ultimate cookie to him: they’re intensely flavoured with cocoa and pull lightly at your teeth. They’re also somewhat magical in their make up – there are no flour, butter or raising agents to contend with, just egg whites, cocoa and icing sugar. A few nuts for bite and a little sprinkle of salt will really help them stand out. What they call for on the side is something silken to dunk them into. If you’re entertaining, these latte custards can be prepared ahead of time and left to rest in the fridge. They’re an absolute doddle to make. And best of all, they’ll make use of the egg yolks you’ve got left over from your cookies. Which is a good thing, since one of the only things The Hungry One doesn’t like is waste.
