Hua Juan is the most common variety of traditional pasta, which is made of hair flour. How to make dough is a headache for many people. Here are two methods of making dough, yeast method and self-raising flour method. From the point of view of nutrition, yeast method is better, because fermented yeast is one of the main food sources of vitamin B needed by human body. Vitamin B can regulate metabolism, maintain the health of skin and muscles, and improve the functions of immune system and nervous system. In terms of fermentation speed and operation difficulty, self-raising flour is more convenient and faster than yeast method. Each of the two methods has its own advantages. As long as you master the skills, you can easily make pasta. The rolls are beautiful in appearance and varied in taste, such as the sweet sesame paste rolls and the salty scallion oil rolls, which we are very familiar with, which are deeply loved by everyone. Here, taking the onion oil flower roll as an example, the making method of flower roll is introduced. Let's take a look at how to make onion oil rolls. Raw materials: fermented dough, onion and cooking oil. Practice: 1. Making fermented dough: Method 1: Take 250g of self-raising flour by self-raising flour method, slowly add warm water, knead it into smooth dough, cover it with plastic wrap and put it in a warm and humid place for 40 minutes before it can be used to make flower rolls. Method 2: 250g of flour, 5g of yeast and warm water 120ml were prepared by yeast method. Warm water is not too hot. Dissolve the yeast in warm water and let it stand for 5 minutes. Slowly pour the yeast water into the flour, knead it into smooth dough, cover it with plastic wrap and put it in a warm and humid place to wake it up until the dough is fermented to about 2-2.5 times. The method to judge whether the fermentation is complete is to dip a finger in flour and poke a hole in the dough, so that the dough will not shrink or sink after pulling out the finger, that is, the fermentation is complete. Note: In summer, the dough can be fermented at room temperature. If the indoor temperature is low, you can put a cup of boiling water in the microwave oven or oven, put the dough in it, or put the dough in a steamer with hot water. You can also put the dough on the heating in winter. In short, we should create an environment with suitable humidity and temperature for the dough to facilitate fermentation. 2. Take out the fermented dough, put it on the panel, knead it to exhaust the gas inside the dough, and then roll the dough into rectangular thin cakes with a rolling pin; 3. Spread the cooking oil evenly on the bread, sprinkle with chopped chopped green onion and appropriate amount of salt. Roll up the bread from one end, roll it into a long roll, and divide it into small rolls with a knife; 4. Pinch the dough roll with both hands, with the opening of the dough roll facing outwards, flatten it and lengthen it, keep the left hand still, twist it into a twist shape with the right hand rotating twice, and then pinch the joints at both ends overlapping. In this way, a flower roll is ready; 5. In the same way as steaming steamed buns and steamed buns, the flower rolls should be placed for about 10 minutes to ferment again. Don't steam them immediately; 6. Put a piece of wet cloth on the steamer and put it into the flower roll, paying attention to leaving a gap between them. Put cold water on the pot, steam after aeration 10 minutes, and turn off the fire. Don't open the lid immediately after turning off the fire, leave it for a few minutes and then open the lid to take out the flower roll.
