Nigella Lawson's spanish macaroons; ground almonds, egg whites and a generous grating of orange zest. Oh, and don't forget the sugar (which i did, but fortunately i whipped them out of the oven in time, and remixed and rerolled .. yes, it is a very obliging recipe).

I made a large batch of these for a party; they have a satisfying crunch on the outside, chewy and moist in the middle. Any remaining will be frozen as they defrost quickly (with no ill-effect) for emergency snacking.
