Set a large Dutch oven over medium heat and add the butter, shallots, garlic, bay leaf and thyme, once the butter has begun to melt, stir the ingredients and place the lid over the pan. Cook for 2 minutes, then add the mussels. Replace the cover and cook the mussels for 1 minute, or until they begin to open. Remove the lid and add remaining ingredients, stir to combine, cover, and remove from the heat. Allow to sit for 2 to 3 minutes, or until all mussels are opened. To serve, divide the mussels between four large soup bowls and pour the cooking juices over the mussels. Serve with crusty, grilled bread.
