Wash clams well. Wash mussels, making sure to remove and discard their beards. Heat 1 tablespoon olive oil in each of 2 large cast iron frying pans over high heat. Add clams and half the thyme to 1 of the pans; add mussels and half of the thyme to the other pan; cook for 1 minute. Divide butter and capers between the 2 pans. Continue cooking clams and mussels for 2 to 3 minutes, or until they open.

To serve, place clams mussels and the butter in which they cooked in a warmed serving bowl and sprinkle with fleur de sel. Serve with bread on the side, to soak up the butter at the bottom of the bowl.

*Cook's Note: If you don't have access to fleur de sel, substitute sea salt.
