Ingredients:
4 cups of basil leaves, tightly packed
4 cloves of garlic
1/4 cup pine nuts
1/2 cup grated parmesan
1/2 cup olive oil
Juice of 1 lemon
dash of red pepper flakes
salt & pepper
Toast the pine nuts. Blend all ingredients except the parmesan, until smooth. Add in the parmesan and blend. Stream in EVOO as needed until smooth. Taste and adjust salt & pepper as needed.
Note: I have also tried making the pesto with pecorino romano for a stronger kick.
