Mixing Ingredients

I was saying the other day about how most baking has four identical ingredients, yet can make so many varied items from them. The four I was referring to were:- flour, sugar, eggs and margarine. There are so many ways to blend and mix them and each gives a different result. Even if different people mix the same ingredients in the same way for a sponge cake when you look at the results all together they are all different.

I wonder who it was that first tried mixing those ingredients and baking them to make cakes, buns, scones, puddings? What made them first try? Who had the idea?

Baking is something we take for granted doing, yet someone first thought of doing it….. when? and where? and who??
