Yeasts are small, single-celled organisms that feed off of simple sugars, breaking them down into carbon dioxide, alcohol (ethanol, specifically), flavor molecules, and energy. The process is referred to as fermentation.

Q. Does yeast feed on starch?
Yeasts feed on sugars and starches, which are abundant in bread dough! They turn this food into energy and release carbon dioxide gas as a result. This process is known as fermentation. The pockets of gas are produced by yeasts when the dough is allowed to rise before baking.
Q. How do you increase yeast fermentation?
How to Maximize the Rate of Fermentation
- Place the mixture being fermented in a warmer area. This is probably the easiest way to increase the fermentation rate.
- Lower the amount of salt and sugar in the mixture. Yeast likes sugar, but not too much.
- Add more water to the mixture to increase the rate of fermentation.
Q. How do you make bread without yeast and baking powder?
Sour Milk. Old milk which has gone sour can be a handy substitute to baking powder. It has a higher acidity that will produce the same effect as that of yeast and baking powder when used in bread baking. Always reduce the amount of liquid in the recipe to ensure the finest texture of the bread.
Q. What can I use instead of baking powder in bread?
Here are 10 great substitutes for baking powder.
- Buttermilk. Buttermilk is a fermented dairy product with a sour, slightly tangy taste that is often compared to plain yogurt.
- Plain Yogurt.
- Molasses.
- Cream of Tartar.
- Sour Milk.
- Vinegar.
- Lemon Juice.
- Club Soda.
Q. Can I use self raising flour instead of plain flour and baking powder?
No. If your recipe asks for plain or self-raising flour, it is important to remember that these two ingredients are not interchangeable and you should use the flour recommended in the recipe along with any raising agents, such as baking powder or bicarbonate of soda.
Q. What happens if I use self-raising flour instead of plain?
Self-raising flour contains baking powder but as baking powder will expire after a period of time you need to use up self-raising flour more quickly than plain flour. In the US self-rising flour also contains added salt which can lead to some of the recipes tasting a little too salty if this flour is used.
Q. Can I replace self-raising flour with plain?
If the recipe calls for plain flour with the addition of baking powder (or another leavening agent), self-raising flour can be used instead, simply omit the leavening agent. If the recipe does not include baking powder or a leavening agent, do not substitute plain flour with self-raising flour.
