A versatile and widely used aromatic herb. Basil is an annual plant that is easy to grow from seed but is very sensitive to cold.
The plant grows well in warm climates and is widely used throughout southern Europe, particularly the Mediterranean, and in many parts of Asia. There are numerous species of basil; some have scents reminiscent of pineapple, lemon, cinnamon or cloves; others have beautiful purple leaves.
The variety called holy basil (tulsi) is an essential part of an authentic Thai curry. In Mediterranean regions, basil and tomato is a classic combination. Pesto, made from basil leaves and pine nuts, with parmesan or pecorino cheese and olive oil (traditionally pounded together in a mortar and pestle – the latter lends pesto its name) is another classic dish.
