What is the main ingredient in traditional pesto?

The main ingredient in traditional pesto is basil. This fragrant herb is crucial to the recipe, providing the distinctive flavor that characterizes pesto. Traditional pesto originates from the Italian region of Liguria, where fresh basil thrives, and it is often combined with other ingredients to create a vibrant green sauce.

While pine nuts, garlic, and olive oil are also essential components of pesto, they serve to enhance and support the flavor of the basil rather than define the dish itself. Pine nuts contribute a creamy texture and nutty undertone, garlic adds a pungent kick, and olive oil binds the ingredients together while providing richness. However, it is the fresh basil that remains the star of the dish, embodying the essence of traditional pesto.
