Holy basil (kaphrao)

Holy basil, Thai kaphrao (also krapao, Ocimum tenuiflorum), is an aromatic herb with a peppery-clove fragrance and a slightly piquant flavour. It looks distinct from sweet basil: smaller, darker, often purplish leaves with a serrated edge. It is the essential ingredient of the Thai dish Pad Krapow (with minced meat, garlic, and chilli) and is also used in Vietnamese and Cambodian cuisines. Add it at the very end of cooking to preserve its essential oils. Not to be confused with Thai sweet basil ho ra pa (anise profile) or with sweet basil.
