Combine sour cream, cheese, lemon juice, onion, salt and Tabasco; mix thoroughly. Pour over crab meat and mix lightly. Place in six well-greased individual shells or custard cups. Combine bread cubes and butter; sprinkle over top of crab mixture. Sprinkle with paprika. Bake in a moderate oven, 350 degrees, for 25 to 30 minutes or until lightly browned. Serves 6.
» Serve with a Beaujolais wine--its light and fruity flavor does not overpower the crab, yet it stands up to the pungency of the parmesan cheese and lemon.
