If you are growing them, the flowers are delicious too. Pick and wash them, let them dry. Make a batter using self raising flour and fizzy water, salt and pepper until it is the consistency of thick double cream and dip the flowers in the batter. Shallow-fry in oil, drain and sprinkle with sea-salt. Delicious!
You can also stuff the flowers with chopped courgette, ricotta, pine nuts, parmesan, basil, lemon zest & oregano. Or you can stuff them with white crab meat, chilli and parsley.
