Bad yeast will completely ruin your bread. Simple trick to see if you can use it

We cannot imagine bread without yeast. But what if we are not sure of its age or quality? Read what you didn’t know about yeast and how to easily test it.

What is yeast?

Yeast, or yeast, is actually living cells of the species Saccharomyces cerevisiae, which need sugar to reproduce. This yeast converts the natural sugars of the flour into alcohol and carbon dioxide. This will later cause the dough to rise.

Is yeast healthy?

Of course. Yeast is mainly rich in vitamin B, especially vitamin B1 (thiamine), B2 (riboflavin), and B3 (niacin). It also contains proteins and some minerals, especially chromium.

Yeast has a beneficial effect on the nervous system, heart activity and skin. It supports the proper functioning of the digestive system and is also beneficial for the eyes. Relieves insomnia and depression.

types of yeast

There are two basic types of yeast: fresh and instant. Fresh yeast should be well packed, light cream in color, crumble easily and smell nice. Store at temperatures from 1°C to 8°C, ideally 5°C. Instant yeast (in sachets) can last up to 2 years. If you had any doubts about the functionality of instant yeast, leave them behind. The principle of swelling is the same. Only it does not contain water, so it will have to be taken differently. It is ideal to use 1 cube of fresh yeast (about 42g) or 1 sachet of instant yeast (10g) per 1kg of flour.

How do you test yeast?

Finally we get to the home test. Sometimes you may not be sure of its applicability. In that case, prepare some lukewarm water, sugar, a mug and let’s go.

Heat the water to approximately 39°C. Pour a little into a cup (about ¼) and mix in a teaspoon of sugar. Stir well until the sugar dissolves, then add 1 teaspoon of the yeast. Stir and leave for 10 minutes. If the mixture rises and forms a soft beige foam, the yeast is good.
