Cakes use butter that is creamed with caster sugar as a means to add small amounts of air so the cake mix rises

into a well formed texture. Ingredients such as butter, margarine or shortening, known as "plastic fat" can be formed into smooth and creamy mixtures with tiny air

pockets that are contained within the fat/ fats.

We know that bakers use it to make the dough 'rise'; without it, our bread would be like flat, hard cakes. In the days when people made their own bread, they would go to a brewer and get a jug of brewer's yeast. It was fluid and yellow. Nowadays, yeast is made commercially on a large scale. The yeast you buy at your market, the yellow lumps done up in paper, has been compressed for convenient handling

Yeast is the ingredient that makes bread rise.

It is a fungus that feeds on sugar. Yeast produces alcohol and carbon dioxide.

Carbon dioxide is the gas that makes the bread rise.

Cooking will destroy the alcohol and the yeast.

The bubbles are left behind and that is what makes bread soft.

To sum upDough is aerated by the action of the yeast. The little cells we mentioned ferment the dough, and produce tiny bubbles of gas inside it. As a result, the dough gets fatter and bigger, and rises, of course. so when the dough is baked, you have a 'bold' loaf, light and airy; when you cut it you can see all the tiny holes formed by the gas, so that it looks like a sponge.

Cakes and sponges aerationThis is achieved by

Whisking the eggs and sugar to incorporate bubbles

Chemical if you use baking powder that produces CO2
