Ingredients:

6 cups of scallops (dried, not washed)
3 cups thinly sliced small mushroom caps
5 tablespoons butter (hard, broken in small dots)
1 heaping cup fresh bread crumbs
fresh ground white pepper
6 shallots, chopped
1/3 cup dry white wine
3 tablespoons lemon juice (fresh)
salt
rock salt
scallop shells

Put the scallops in a large bowl, season with  salt, pepper, wine, shallots  and lemon juice. Mix well, sprinkle with bread crumbs; reserve about 3 tablespoons for later use.   Toss everything together quickly, add 2/3 of the butter dots.  Mix lightly. Butter 6 scallop shells, place them on rock salt.  fill each one equally with the scallops, sprinkle the remaining bread crumbs, topped with the rest of the butter dots.  Bake in a very hot oven for 12-15 minutes or until golden brown. Serve immediately with thin cucumber or watercress tartines. Serves 6.  Thanks to Chef Marcel Kein  (Chef at the Ritz  Carlton Hotel in Boston, 1972)
