Science in the Kitchen - Bread Part 1

Yeast. It's all yeast these days!

Liam and I are continuing our studies in the kitchen. We've exhausted our studies of the egg and we are moving on to bread! Look out hips, here comes another 5 pounds.

We started our studies by discussing leavening agents. We made some cookies and muffins using baking soda and baking powder. But everyone knows that the Mack-daddy of leavening agents is yeast. And yeast is so entertaining. First question of the day....."does yeast like sugar?"

We did a quick little experiment by using equal amounts of yeast and warm water in two separate bowls. In one bowl we also included a teaspoon of sugar. Can you guess which bowl had the sugar?

If you guessed the bowl on the left, then you are right. In the same amount of time, the bowl with sugar created huge amounts of yeast foam compared to the bowl without the sugar. So the next time you make a yummy bread, be sure to proof your yeast with sugar.
