Mix butter, milk & bread. Stir in salmon, egg yolks, lemon juice, onion, salt & pepper. Beat egg whites till stiff & fold into salmon mixture.
Pour into greased 1 1/2 qt casserole dish, sprinkle w/paprika & bake uncovered for 1 hour.
NOTE: If served as a starter, I favor the use of ramekins or sml individual souffle dishes, but watch carefully as I do not know how this will chg cooking time.
HINT: To easily shave smoked salmon, put it in the freezer. When nearly frozen, remove from the freezer & use you sharpest knife to shave very thin slices. Then dice them into sml pieces for this recipe.
