Capers are the small, green, unopened flower buds of the caper bush (Capparis spinosa), a perennial plant native to the Mediterranean region, but widely cultivated in other parts of the world. These edible buds are known for their distinctive, tangy flavor, which adds a zesty, savory element to a variety of dishes. They are commonly used as a garnish, seasoning, or pickled in vinegar or preserved in salt brine to prolong their shelf life.
In culinary applications, capers are often incorporated into Mediterranean cuisine, particularly in Italian, Spanish, and Greek dishes. They are a popular ingredient in sauces, dressings, pasta, and salads, as well as pairing well with fish, poultry, and meat. Capers also offer potential health benefits due to their high antioxidant content and anti-inflammatory properties.
