What is Yeast?

Yeast is an essential ingredient used in baking items such as breads, rolls, and pizza crust. It is an agent used to cause breads to rise. Scientifically, yeast is a single celled microorganism that grows through a process called budding.

How Does Yeast Work?

When purchased in the store, yeast is typically in a dried state, and the moisture has been removed from it. But activate the yeast by putting some moisture back into it, as well as some warmth and you’ll have yeast that thrives. Yeast feeds on the sugars and flour and releases carbon dioxide that makes bread rise.

How to Store Yeast

The proper storage for yeast will help to maximize its shelf life as much as possible. Unopened packets of yeast should be stored in a cool and dry place, away from sunlight and temperature fluctuations.

How To Check If Yeast Is Still Good

You’ll only want to use yeast that is still active. Otherwise, your dough won’t rise. First check the expiration date on your yeast packaging to confirm that it hasn’t expired.

Then, mix a few tablespoons of warm water with your yeast, along with a pinch of sugar. This will activate the yeast if the yeast is still good. Wait 5 minutes and if the mixture begins to get bubbly, then the yeast is still good. If nothing happens and no foam appears, the yeast should be thrown away because it won’t make your dough rise.

What Are the Different Types of Baking Yeast?

There are four main types of baking yeast as follows. Each of these kinds of yeast can be used interchangeably. The type doesn’t matter based on what kind of bread you’re making. Each is a matter of personal preference and convenience.

Active Dry Yeast. Active dry yeast is yeast that has been processed and has had the water from it removed. It needs to be dissolved in whatever warm liquid is in your recipe first, before adding it to the mixture.

Instant Yeast. Instant yeast works a little faster than active dry yeast, and doesn’t need to be dissolved in water first.

Quick-Rise Yeast.  When using quick-rise yeast, your bread dough only has to rise once rather than twice like some recipes might instruct. It does not have to be dissolved first before being added to the mixture.

Cake Yeast. Cake yeast is a form of fresh yeast that needs to be refrigerated at all times and needs to be dissolved in warm liquid first.
