A simple, comforting side dish that combines Jiffy corn muffin mix with canned corn, sour cream, and butter for a creamy, custard-like texture with a crispy top.
Do not drain the canned corn juice; it is essential for the custard texture. Use a 9×9 inch pan for the correct depth; a 9×13 pan will result in a drier casserole. Let the casserole rest for 10 minutes after baking to allow it to set properly. Room temperature ingredients help create a smoother batter.
