i have the julia childs french cookbooks and a modern joy of cooking. there are many sponge ckaes and i am not a very expeirenced baker. i like the flavor profile of this caribbean cake and i just wondered how the techniques and ingredient ratios compared to the classic french, english and germanic or central european sponge cakes. here is the recipe Marble Cake | Simply Trini Cooking is this standard? can it be tweaked?
