What is Pesto and Its Healthy Ingredients?

Pesto, a versatile and delicious sauce, originated in the Liguria region of Italy. The word 'pesto' translates to 'hammered' or 'mashed,' reflecting its traditional preparation method using a mortar and pestle. Pesto is typically made with a combination of fresh herbs, nuts, garlic, and olive oil, among other ingredients. While the most common version includes basil, pine nuts, garlic, and olive oil, there are numerous variations to suit different tastes and dietary needs.

For instance, pesto can be made with nuts like walnuts or almonds, or even without greens using ingredients such as lemon, garlic, and ricotta cheese. This flexibility makes pesto a versatile ingredient in both traditional and modern cooking.
