1. Preheat the oven to 375°. In a large mixing bowl, combine the clams, onion, parsley, Worcestershire sauce, melted butter, salt and a few grindings of black pepper. Stir in the crushed soda crackers and ½ cup of the fresh bread crumbs, pour in the cream and mix together gently but thoroughly.
2. Taste for seasoning. Transfer the mixture to a lightly buttered 1-quartcasserole and sprinkle the remaining bread crumbs over the top.
3. Dot with the 2 tablespoons of butter and bake in the center of the oven for about 25 minutes, or until the crumbs are lightly brown.
4. For a crisper, browner crust you may, if you like, slide the casserole under a preheated broiler for 30 seconds or so. Serve as a first course or luncheon dish directly from the casserole.
