Cake recipe without baking soda (basic recipe):
- one cup of flour
- one cup of sugar
- one egg
- tablespoon of boiling water
Cake with yeast?
* Look here on sugar beets. Seems some chemicals are necessary for sugar extraction after all. Like chalk. Is beetroot sugar an invention from Kent, England? But it seems cassonade/brown sugar does not depend on it.
And yes, I completely forgot about maple sirup!
