Edible flowers are great for adding colour and peppery flavour to dishes. The nasturtium is an annual flowering plant whose edible leaves and orange, red and yellow petals have a flavour that is similar to watercress. The flower buds and seeds, picked when soft and pickled in vinegar, can be used as a substitute for capers.
You’re most likely to find nasturtiums at specialist food shops or farmers’ markets.
Sprinkle them in salads or use as a garnish for any savoury to dish to add colour and bite.
