Capers are pickled flower buds. Tiny capers are picked from a shrub-like bush (Capparis spinosa), long before the buds ever flower. The capers are then dried in the sun and later brined or packed in salt.
Dried caper is valued for the burst of flavor it gives to dishes. It adds texture and tanginess to a great variety of recipes, including fish dishes, pasta, stews, and sauces.
