One of the most popular culinary herbs is sweet basil. Fresh leaves may be stored in a cool place or in the refrigerator for a very short time. 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. Add fresh herbs only at the end of cooking or upon serving. Many species of the basil herb exist, but the most popular is sweet basil. Basil is considered one of the most important and highly used herbs in the culinary world and is popular in the cooking of many types of cuisine. 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.
