Required materials: baking soda (1 serving), white vinegar (1 serving), clear water (3 serving) and appropriate amount of white sugar.
The specific method is as follows:
1, prepare a bowl, and add a proper amount of baking soda and white vinegar, because baking soda and white vinegar can form surface alkali when mixed. Add 3 times as much water as them, stir them evenly with chopsticks, and set them aside for later use, as shown in the following figure:
2. Prepare a small basin, put in the right amount of flour, add the right amount of white sugar (white sugar is added to make it more sweet and delicious), stir it evenly with chopsticks, make a groove in the middle, and pour the prepared flour alkali solution into the small basin in a small amount of times. Stir them evenly, as shown in the following figure:
3. When the flour in the basin has formed dough, rub it repeatedly by hand. Then seal the small basin with plastic wrap, keep it away from the air, and put it in a warm place to make dough. It only takes 10 minutes to "fill the basin", as shown in the following figure:

leaven
There are three kinds of leavening agents: baking soda, flour fertilizer (old flour) and dry yeast powder. They all work on the same principle: under the right conditions, the starter produces carbon dioxide gas in the dough, and then the dough becomes soft and delicious by being heated and expanded.
1, baking soda is not rich in gas, so the softness of the finished product with it is not very good. Moreover, it is a weakly alkaline substance, which will destroy the vitamins in flour and reduce the nutritional value of pasta.
2, flour fertilizer is also called old noodles in some places. It is a piece of dough left after the last fermentation. After proper preservation, it is used as a strain to start fermentation. Flour fertilizer must be used with alkali because it will make the dough sour.
3. Active dry yeast (yeast powder) is a natural yeast extract, which is not only rich in nutrients, but also rich in vitamins and minerals.
