Basil is a fragrant herb commonly used in Italian cuisine. It has a sweet and slightly peppery flavor that adds a burst of freshness to dishes. It pairs well with tomatoes, making it a staple in many pasta sauces and salads. Basil is also a key ingredient in pesto, a popular Italian sauce made with basil, garlic, pine nuts, and olive oil. In addition to its culinary uses, basil has medicinal properties and is believed to have antioxidant and anti-inflammatory effects.
