Capers are one of the gems of the Mediterranean diet. In cooking, the leaves, berries, and unopened flower buds of the caper plant are used. Royal caper is the small unopened flower bud of the plant. It is dark green in color and may have white spots on its surface. Salty, tangy capers are suitable for any dish. In Mediterranean countries, they are used to season and garnish salads, pastas, and pizzas. Try them also in omelets, potato salad, and with fish and chicken dishes.
