Baked Spoon Bread
If you do not have cornmeal then you can often substitute flour or cornstarch for it. But it all depends on the recipe. I would usually use cornstarch.
Half-and-half can be used in place of the light cream.
If you don't have white pepper, you can use black pepper.
You can also put bacon or pineapple or whatever you like in it.
You can put any kind of meat that is shredded, pulled apart, and cooked.
