Over medium heat in a skillet, cook the walnuts and whole garlic cloves, unpeeled.
¼ cup walnuts, 2 cloves garlic
Shake the pan to ensure even toasting. After 1-2 minutes, remove the nuts.
Toast the garlic for an additional 1-2 minutes. Remove from the pan, peel the garlic, and allow to cool.
In a blender, add the basil, nuts, garlic, olive oil, lemon zest and juice, and blend together until you reach a texture that is decently smooth but still slightly chunky.
2 cups fresh basil, ¼ cup olive oil, ½ teaspoon lemon zest, ½ teaspoon lemon juice
Place the mixture into a small bowl and stir in the parmesan cheese and a pinch of salt with a spoon.
¼ cup parmesan cheese, 1 pinch salt
