Instructions
- Step 1: Scrub 1.5 lbs mussels under cold running water, removing any beards, and discard any that are open or cracked—these are not fresh.
- Step 2: In a large pot, melt 2 tbsp unsalted butter over medium-high heat. Add 2 minced garlic cloves and 1 thinly sliced medium leek, sautéing for 3 minutes until the leek is softened and fragrant.
- Step 3: Pour in 1/2 cup dry white wine, bring to a gentle boil, and add the mussels. Cover tightly and steam for 5-7 minutes, shaking the pot occasionally, until all mussels have opened—discard any that remain closed.
- Step 4: Remove mussels from pot with tongs, reserving 1/2 cup of the cooking liquid. Stir 1/4 cup heavy cream and 2 tbsp fresh tarragon into the pot, simmering for 2 minutes until the sauce thickens slightly and coats the back of a spoon.
- Step 5: Return mussels to the pot, tossing to coat in the sauce. Season with 1/4 tsp freshly ground black pepper and 1 tbsp fresh parsley, cooking for 1 minute more until heated through.
