Brewer's yeast vs. baker's yeast: What's the difference?

Dear Lisa: Baking is my hobby. Please tell me how much brewer's yeast should I use in one cup of flour. Thank you. Anju Khare

Dear Anju: There are hundreds of strains of yeast in the world, and certain varieties have been developed to give optimal results for their selected uses.

Baker's yeast has been perfected to give optimal results in bread recipes, but it is possible to use brewer's yeast in bread-making as well. Just be aware the dough made with brewer's yeast will require much longer rising times.

Brewer's yeast is so named because it is the same fungus that is used to ferment and make beer. It tastes bitter, but many like to use it as a protein supplement and energy booster.

If you have yeast from a home-brew supply store, you'll find that the various types of yeast -- say lager yeast or ale yeast -- will impart subtle flavor differences in your bread.

Nutritional yeast -- which is often confused with brewer's yeast -- is also available.

Nutritional yeast is a vegetarian dietary supplement that is rich in vitamins and protein. Many people prefer the flavor of nutritional yeast, as it is sweeter and more closely resembles Parmesan cheese. Sprinkling it on popcorn is popular.

As for the amount of brewer's yeast you will need, 2 teaspoons per pound of flour will suffice, or 1/2 teaspoon per cup.
