Pesto

Pesto is a vibrant, herbaceous sauce traditionally made from fresh basil leaves, pine nuts, garlic, Parmesan cheese, and olive oil. It is typically bright green in color and has a fresh, slightly salty, and savory flavor profile. The texture ranges from finely ground to slightly chunky, depending on the preparation method. Pesto is a versatile ingredient that enhances the flavor of various dishes.

History

Pesto originated in Genoa, Italy, in the Liguria region. The name comes from the Genoese word 'pestâ,' meaning 'to pound' or 'to crush,' referring to the traditional preparation method using a mortar and pestle. It was initially a peasant food, utilizing readily available ingredients. Over time, pesto's popularity spread throughout Italy and then globally, adapting to different regional variations and culinary preferences. Pesto's cultural significance is tied to its fresh ingredients and the communal aspect of preparing it, often reflecting a connection to the land and local produce.

Common Uses

  • Tossed with pasta (classic use)
  • Spread on sandwiches or used in wraps

Storage Tips

Store pesto in an airtight container in the refrigerator. Properly stored, homemade pesto typically lasts for 3-5 days. To prevent oxidation and browning, cover the pesto surface with a thin layer of olive oil. Frozen pesto can be stored for up to 3 months; portion it into ice cube trays or small containers for easy use. Thaw frozen pesto in the refrigerator overnight or at room temperature for a short period.
