Ingredients
1⁄8 cup pine nuts, toasted
1⁄2 large garlic clove, peeled
1⁄4 cup flat leaf parsley, tightly packed
1⁄2 cup celery leaves, tightly packed (choose the tender leaves)
1⁄8 teaspoon salt
1⁄2 cup olive oil
1⁄8 cup parmesan cheese, freshly grated
zest of 1⁄2 lemon
juice of 1⁄2 lemon
Method
Chop the pine nuts, garlic, parsley, celery leaves, and salt together in a food processor until the mixture becomes a smooth paste. Slowly drizzle in the olive oil.
Add the cheese, lemon juice, and lemon zest, mixing well to incorporate.
Season to taste with salt.
If you like your pesto less lemony, I recommend adding the lemon juice a little at a time until just right.
