Watercress pesto

Watercress pesto is a delightful variation of the classic basil pesto, offering a peppery twist and a vibrant green color. This recipe combines the distinct flavors of watercress, walnuts, and Parmesan cheese, providing a rich and aromatic sauce that pairs perfectly with pasta, sandwiches, or as a spread for appetizers.

Instructions:

1. Toast the Walnuts:
- Begin by toasting the walnuts to enhance their flavor. Place them in a dry skillet over medium heat. Cook, stirring frequently, for about 3-5 minutes until they are fragrant and lightly browned. Remove from heat and let them cool.
2. Prepare the Food Processor:
- In a food processor, combine the toasted walnuts, watercress, and garlic cloves. Pulse until the mixture is finely chopped.
3. Add Olive Oil:
- With the processor running, slowly add the olive oil in a steady stream. Continue to blend until the mixture is well combined and smooth.
4. Incorporate Parmesan Cheese:
- Add the grated parmesan cheese to the food processor and pulse a few times until fully integrated into the pesto. If the consistency is too thick, you can add a bit more olive oil to reach your desired texture.
5. Season to Taste:
- Taste the pesto and season with salt and pepper as needed. You can also adjust the other ingredients to suit your taste preferences (e.g., more garlic for extra punch).
6. Store or Serve:
- Transfer the watercress pesto to a jar or airtight container. It can be stored in the refrigerator for up to a week. If you plan to store it longer, you can cover the top of the pesto with a thin layer of olive oil to preserve its color and freshness.

With its unique flavor profile and vibrant appearance, watercress pesto is a versatile and nutritious alternative to traditional pesto. By following this simple recipe and tips, you can create a delicious condiment that elevates a variety of dishes, adding both taste and visual appeal.
