Miso Butter Spaghetti with Scallions

Miso and garlic deliver a flavor upgrade to that classic kid food—buttered noodles. Softened butter mixed with miso, garlic, scallion whites and lemon juice creates a simple, flavorful no-cook sauce for pasta. The heat from the noodles and some of the starchy pasta cooking water melts the butter, creating a silky coating. Use mild white miso, assertive red miso or a combination. Spaghetti or linguine are good here, but short gemelli and casarecce also work. If using a short pasta, start by adding only 2 tablespoons pasta water when tossing the noodles with the butter mixture.
