Capers are the edible flower buds of Capparis spinosa, a bush native to the Mediterranean. You’ll find them in jars at the supermarket pickled in vinegar or brine, so give them a rinse before use. Capers add bite to salads, play a key role in tartare sauce, and complement fish well.
Less widely used are the larger caperberries: a grown-up, spinsterish version of the caper.
