I know that many people have their own favorite recipe but I will throw mine out here just in case someone needs one.
2 cups fresh basil leaves, packed
1/2 cup freshly grated Parmesan (you can use Romano as well)
1/2 cup extra virgin olive oil
1/3 cup pine nuts, walnuts, or pecans
3 medium sized garlic cloves
1/2 teaspoon sea salt
1/2 teaspoon freshly ground pepper ( I like to use white pepper but black works as well)
