Poached Mussels For Two Recipes

Steps:

• Melt butter in a medium high-sided saucepan over medium heat. Add shallots and garlic, and cook, stirring, until shallots are translucent and garlic is very fragrant but not brown, about 2 minutes. Add the salt and pepper. Add mussels and wine. Cover saucepan, and cook until mussels open and are cooked through, about 8 minutes. Discard any mussels that have not opened.
• Remove mussels from saucepan. Transfer cooking liquid to a small bowl, and set aside to cool. When cool, transfer to refrigerator to chill.
• Remove mussels from shells, reserving shells for serving, if desired. Place mussels in a small bowl, cover with plastic wrap, and transfer to refrigerator.
• Whisk together creme fraiche, mustard, and champagne vinegar. Stir cooking liquid, and add about 4 tablespoons reserved cooking liquid and shallots to the creme fraiche mixture to make a nice thin sauce with just enough body to cling to mussels. Adjust seasoning with salt and pepper and more mustard if desired. Stir in half the lemon zest and chervil.
• Gently toss cold mussels in mustard sauce. Spoon a mussel and a large puddle of sauce back into reserved mussel shells. Sprinkle mussels with remaining half of zest and chervil, and serve with any remaining sauce on the side.
