Caper berries are the fruit of the caper bush and a speciality of Andalucia, where they are most often lightly pickled in sherry vinegar and brine. The caper bush grows wild in arid volcanic soil or, as often happens, in crumbling walls, having the same ability to grow in the most inhospitable habitats as our native buddleia. The berry is the false fruit, containing the seeds – its true fruits. The best way to eat caper berries is uncooked and straight from the brine as a nibble with a glass of chilled fino, a delicious combination.
