I bake a few cakes regularly. Most of the recipes can be found online, but I usually have found some tweaks that make them taste better (subjective). So I make notes of them in my little book.

I think most recipes are derivative. You have to start somewhere when you make cornbread. So why not start with a standard recipe. Then you substitute some ingredients because you're missing something at home. You find it either tastes better or worse. Then you can improve the recipe.

In the end my cornbread recipe only has 2 different ingredients that give it better texture and better aroma. It's still almost the same recipe.
