Ingredients

1 cup packed spinach leaves, rinsed well 

1 cup packed basil leaves 

1/4 cup grated Parmesan or Romano cheese 

1 teaspoon chopped garlic 

1/3 cup extra-virgin olive oil 

2 tablespoons toasted pine nuts 

Coarse salt and freshly ground black pepper 

Preparation

Bring a medium pot of water to a boil. Prepare an ice-water bath and set aside. Place spinach leaves and basil in a colander or strainer; pour boiling water over spinach and basil. Immediately transfer to ice-water bath to cool. Squeeze leaves together to extract as much water as possible.

Transfer spinach and basil to the bowl of a food processor along with cheese, garlic, olive oil, and pine nuts. Process until a smooth paste is formed; season with salt and pepper. Use immediately or store in an airtight container, refrigerated, for up to 5 days.
