Preheat oven to 350 degrees. Butter and dust with bread crumbs a 1-quart souffle dish or 4 (8-ounce) ramekins. Coarsely chop smoked salmon and put aside, or if using canned salmon, thoroughly drain the salmon. In a bowl, clean bones and skin from salmon. Break it into fine pieces with a fork. Set aside. Place all remaining ingredients in a blender container. Cover and blend at medium speed for about 30 seconds. Blend at high speed for another 10 to15 seconds. Stir the egg mixture into the bowl with the salmon. Pour the mixture into the prepared souffle dish or spoon the mixture into the prepared ramekins including an equal amount of salmon pieces in each. Bake for 45 minutes to 50 minutes on a cookie sheet, until puffy and delicately browned. Don't open oven door for at least 30 minutes. Serve immediately.
