For a home-made basic pesto (this yields about 2 cups), combine 4 cups of fresh basil leaves, 1/4-cup of pine nuts or walnuts, and 4-5 cloves of garlic in a food processor. Pulse about 8 times or so until the basil of finely chopped. Add about 1/3-cup of grated Parmesan cheese (can be Romano). Let the food processor run and slowly drizzle in 1/2-cup of olive oil. Once it's smooth and creamy add a dash of red pepper flakes and a pinch of salt. Taste and add more salt & pepper as you wish.
