Ingredients

1 cup walnuts or pine nuts 

Coarse salt and ground pepper 

8 cups (4 ounces) lightly packed fresh basil leaves 

2 garlic cloves, coarsely chopped 

2/3 cup extra-virgin olive oil 

Preparation

Preheat oven to 350 degrees. Spread nuts evenly on a rimmed baking sheet; toast in oven until golden and fragrant, tossing once, 8 to 10 minutes. Let cool completely.

Meanwhile, bring 4 cups salted water to a boil; add basil, and submerge with a spoon. Immediately drain in a colander. Rinse with cold water until cool, then pat basil completely dry in paper towels.

In a food processor, combine nuts, basil, and garlic; season generously with salt and pepper. Process until nuts are finely chopped. With machine running, pour oil in a steady stream through the feed tube; process until smooth. Use immediately, or freeze.
