How to Make It
Heat butter and oil in a large Dutch oven over medium-high. Add shallot and garlic; cook, stirring often, until starting to soften, about 3 minutes. Add turmeric; cook, stirring constantly, 30 seconds. Stir in wine, pepper, and salt. Bring to a boil; cook 1 minute. Add mussels; cover, and cook until shells open, about 3 minutes, shaking Dutch oven once or twice during cooking time. Remove and discard any unopened mussels. Divide mussels and broth evenly among 4 bowls; sprinkle with parsley.
