Beat eggs until light. Blend in sugar, sour cream, milk, salt, cinnamon, ginger, prunes and noodles. Heat butter until bubbly in 8" x 13" pan. Spoon approx half of butter into noodle mixture, leaving enough in pan to brown kugel well. Spoon in kugel; bake uncovered at 350 degrees for 70-90 minutes or until crust is quite crisp.
Optional- substitute 20 oz can crushed pineapple, well drained, for prunes.
