Capers are small edible flower buds from a Mediterranean bush called Capparis Spinosa. They are generally pickled in brine or vinegar. The two main varieties of capers are the non-pareil caper and the caper berry. Non-pareil capers are the smallest variety, measuring only around 2-3mm in diameter. They have a tangy, acidic flavor and are typically used as a seasoning for many dishes like sauces, salads, and fish. Caper berries, on the other hand, are about three times larger than non-pareil capers and measure around 6mm in diameter. Unlike non-pareil capers which usually come pickled, most caper berries can be eaten whole because of their larger size and softer texture. They have a milder flavor than non-pareil capers, ideal for salads or simply served as an appetizer with cheese or olives.
