Ingredients

2 cups fresh basil leaves, thoroughly washed and patted dry
4 good-size garlic cloves, peeled and chopped
1 cup shelled walnuts
1 cup olive oil
1 cup freshly grated Parmesan cheese
1/4 cup freshly grated Romano cheese
Salt and freshly ground black pepper, to taste

Directions

Combine basil, garlic and walnuts in the bowl of a food processor and chop (or halve the recipe and use a blender). Leave the motor running and add the olive oil in a slow, steady stream. Shut the motor off, add the cheeses, a big pinch of salt and a liberal grinding of pepper. Process briefly to combine, then scrape out into a bowl and cover until ready to use. Makes 2 cups, enough to sauce 2 pounds of cooked pasta.
