I do a casserole which doesn't particularly use leftover but here it is...
1can corn - undrained
1 can creamed corn
1 pkg of jiffy corn muffin mix
1 stick butter or margarine
2 eggs beaten
1/2 c sour cream
Mix all togher in 2 qt casserole. Bake 350 for 45 min.
I chop up the butter into large chunks and mix in after cooking for a bit. It also takes longer to cook -about 1 hr. Everyone raves about it and requests the recipe.
Enjoy.
