Penne with Toasted Nut and Parsley Pesto
From America's Test Kitchen Season 5: Quicker Pasta
Serves 4 to 6
Toasting the unpeeled garlic in a skillet reduces its harshness and gives it a mellow flavor that works well in pesto. The pesto can be stored in an air-tight container in the refrigerator for up to 3 days.
