Green pepper, like black, is made from the unripe drupes. Dried green peppercorns are treated in a way that retains the green colour, such as treatment with sulphur dioxide, canning or freeze-drying. Pickled peppercorns, also green, are unripe drupes preserved in brine or vinegar. Fresh, unpreserved green pepper drupes, largely unknown in the West, are used in some Asian cuisines, particularly Thai cuisine. Their flavour has been described as spicy and fresh, with a bright aroma. They decay quickly if not dried or preserved.
