Pesto
Pesto is a vibrant green sauce originating from Genoa in the Liguria region of Italy. Known for its rich flavor, it is traditionally made from crushed garlic, European pine nuts, coarse salt, basil leaves, and Parmigiano-Reggiano blended with olive oil.
History
- Origin: The name "pesto" comes from the Italian word "pestare," which means to pound or crush, referring to the original method of preparation using a mortar and pestle.
- Early Mentions: The first mention of a pesto-like sauce dates back to the 19th century. However, similar recipes existed in Roman times, where a paste made from cheese, herbs, and oil was mentioned in culinary texts.
- Traditional Recipe: The classic recipe for Genoese pesto was formalized in the late 19th century, and it has been protected by the Consortium of Pesto alla Genovese since 2000.
Ingredients
- Basil – Traditionally, Genovese basil, which is known for its sweet, slightly peppery flavor, is used.
- Pine Nuts – These add a subtle sweetness and a creamy texture.
- Garlic – Provides the base aromatic flavor.
- Parmigiano-Reggiano – A hard, aged cheese that adds depth and richness.
- Pecorino Sardo or Pecorino Romano – Sometimes used along with Parmigiano for a sharper taste.
- Extra Virgin Olive Oil – Essential for its fruity flavor and to bind the ingredients.
- Salt – Enhances the flavors of other ingredients.
Preparation
The traditional method of making pesto involves:
- Using a mortar and pestle to crush garlic with salt, then adding basil leaves gradually.
- Incorporating pine nuts, followed by cheeses.
- Finally, slowly adding olive oil to create a creamy consistency.
Today, many people use a food processor or blender, which significantly reduces preparation time but might alter the texture slightly.
Variations
While the traditional recipe from Liguria is well-known, variations of pesto exist:
- Pesto alla Siciliana (or Pesto Rosso) includes tomatoes and almonds instead of pine nuts.
- Pesto alla Trapanese uses tomatoes, almonds, garlic, and basil.
- Modern variations might substitute basil with other herbs or greens like spinach or kale, or use different nuts such as walnuts or cashews.
