Another exception is parmesan crisps. In fact, I've just made a tray of them to be nibbled with our aperitif ce soir. Get a big baking tray and line it with greaseproof paper. Put little piles of grated Parmesan, heaped tablespoon-size, all over it. Big gaps not needed. Bake at 180C for seven minutes. Maybe eight. Careful - a minute too long and they burn. Very nice with a bowl of olives and an Aperol spritz.
