Warm courgette salad with mushrooms and marjoram

Courgette flowers are tender and delicate in flavour and can be included raw in a summer salad. The flowers are either male or female and both are good to eat: the males blossom on the end of a slender stalk with no sign of swelling; females convert their stalks into the fruiting body, swelling just behind the blossom. If you grow your own, crop the males as soon as they come into bloom to give the females a better chance to mature.
