Pasta with Garlic Stems and Basil

This juicy green allium, which has little of garlic’s aggressive aspect (as is evident from the equal weight of penne and garlic stems!), plays vegetable and seasoning in a fresh pasta toss. Choose pasta that mimics the pretty, slim slices, such as narrow quills (penne), or another form of the same length, such as gemelli. For a variation, omit the lemon and toss the hot pasta with halved small cherry tomatoes (at room temperature, not chilled).
