What kind of yeast do you have
There are many kinds of yeast, such as beer yeast, tea yeast, hairstyle yeast, fresh yeast, high sugar resistant yeast, etc. I don't know too much about it. Let's talk about baking alone. Yeast is a kind of unicellular fungal microorganism and a kind of biological bulking agent beneficial to human body. The mechanism of dough making is that yeast metabolizes in dough, produces nutrition and flavor substances that are beneficial to human absorption, and produces CO2 gas, which makes dough swell, soft and delicious. But the hair noodles many people hair is not good, said sends out the acid or the hard, is not soft enough. Yeast like a warm environment, generally around 30 degrees, a certain humidity is the most appropriate. When it's cold, the small partners in the north have heating at home. Don't worry about it at all. As long as you watch the time, the dough won't be a problem. Southern partner, there is no heating at home, the temperature is low, hair should pay attention to the temperature. If you have a foam box, take 2 basins, a kneading surface, one filled with boiling water, put it in a foam box, cover the lid for half an hour, and the noodles will be ready in an hour. If there is no foam box, wrap the dough tub in a towel, and put a water bar together in the quilt. Good hair, with your fingers press the dough, the dough does not rebound.
Angel's high activity dry yeast is the most commonly bought in the market. It is usually available in supermarkets. It's cheaper to buy one bag for one dollar. You can pack as many bags as you want. This kind of yeast is suitable for making steamed buns, not bread. It is suitable for people who occasionally make pasta. However, people who often make pasta recommend large package of high sugar resistant yeast. The reason will be explained later.
High sugar tolerant yeast is recommended by myself. Experts call it high sugar yeast which is suitable for surviving in the sugar concentration of more than 7% (in flour) as high sugar yeast, and vice versa as low sugar yeast. You can't make bread with this kind of yeast. Please remind me. High sugar resistant yeast brands generally have gold swallow Angel gold. Why do we recommend high sugar tolerant yeast? Because high sugar tolerant yeast can be used to make bread or steamed bread, and it has a long storage time, so there is no particularly strict requirement on the environment.
Now there is fresh yeast, which we like to use. It tastes good. It needs to be refrigerated or frozen, which can be preserved for 45 days. If it is frozen, it can be preserved for about a year, but it will lose the activity of yeast.
