Chef's Tip: After cooking the clams, strain and freeze the broth. Use it for seafood soups.
Place the wine, shallots, garlic and herbs in a large saucepan. Bring the liquid to a boil. Add the clams to the broth. Cover and cook, shaking the pan occasionally, 5 to 7 minutes or until you begin to hear the clams popping open. Remove the opened clams to a bowl. Cook any unopened clams a little longer. Discard any that refuse to open. Let the clams and the cooking liquid cool slightly.
In a large bowl, stir together the butter, the panko crumbs, parsley, ham, shallots, garlic, chives and salt and pepper to taste. Mix well.
Remove the clams from their shells. Place half the shells in a large baking pan. If the clams are sandy, rinse them by dipping one at a time into the cooking liquid. Place a clam in each half shell. Generously spoon the filling onto each clam, approximately 1 teaspoon per clam. Sprinkle the tops of the clams with the remaining crumbs, approximately 4 tablespoons.
Preheat the Broiler. Place an oven rack about 4 to 5 inches from the broiler heat source. Broil 1 to 2 minutes or until browned. Serve hot.
