Basil

One of the most populary culinary herbs is sweet basil. The best flavor of purple basil comes from the Red Rubin variety. Especially good in Thai dishes is the Thai Basil whose leaves have a spicy aniseed aroma with hints of mint and citrus (most often used in Pesto). 
Basil is available in fresh leaves and in dried leaves, which are also sometimes called rubbed. Also indispensable for many Mediterranean dishes, the fresh leaf has a sweet, clovelike spiciness and is excellent with tomato dishes. Its flavor is strong enough to stand up to the pungency of garlic, so it is often paired together like in Pesto.
The strong, clove like flavor is essential to many Italian recipes and it is paired most often with tomatoes. Basil is primarily used in sauces, pizzas, salads and pasta dishes. It is also the main ingredient used in pesto.
