Fresh nasturtium flowers (Tropaeolum majus) are brightly colored edible flowers with tender petals and a distinctive peppery flavor reminiscent of watercress or mustard. Flowers range from pale yellow and golden orange to deep red, with their colors reflecting different mixtures of carotenoids and anthocyanins. Nasturtium flowers contain glucosinolates and their pungent breakdown products, along with flavonoids, hydroxycinnamic acids, carotenoids, and other polyphenols. Their vibrant color and fresh, peppery flavor make them especially useful for salads, grain bowls, appetizers, herb sauces, and garnishing savory dishes.
