Courgette flowers can seem hard to get hold of, but any good greengrocer will have them and they're worth the effort of tracking them down.
Tip
Courgettes were actually first grown in Mexico. Over there, they are so plentiful that their flowers are sold in great big bundles in the markets, and are eaten in cheesy quesadillas at every other street food stand. They look wonderful laid out on an omelette, but you can just use courgettes if you are struggling to get hold of the flowers.
