1. The dough is hard and lacks water, and the typical formula ratio problem is to add more water. The specific amount of water to be added depends on the water content of the flour, and there is no fixed amount, which needs to be determined based on experience. Li Ji used Wudeli 6-star flour to make steamed buns, adding 51% water, which is 255 grams of water per kilogram of flour.

2.和面后静置，这个工艺很重要，李记一般和面后要将面团在和面机里静置1-3分钟，让面筋充分舒展一下，就跟人早起伸懒腰的意思差不多，和面后面团的面筋是相对紧张的，如果不充分舒展后就成型的话，很容易面筋就断了，导致成型的时候包子馒头开裂。

2. The process of standing after dough mixing is very important. Li Ji usually puts the dough in the dough mixing machine for 1-3 minutes after dough mixing to fully stretch the gluten, which is similar to getting up early and stretching. The gluten of the dough after dough mixing is relatively tight. If the dough is not formed after fully stretching, it is easy to break the gluten, causing the Mantou to crack when forming.

3.压面或包制时要少放干粉，干粉太多的话，成型的时候容易开裂，在成型时要保证面团的湿度，可以用湿布盖在面团或剂子上。这点属于细节问题，说起来没啥技术含量，但有的时候，包子馒头出现的问题，往往原因就在细节上。

3. When pressing or packaging, it is necessary to put less dry powder. If there is too much dry powder, it can easily crack during molding. During molding, it is necessary to ensure the humidity of the dough, and a damp cloth can be used to cover the dough or formulation. This is a detail problem. It doesn't have much technical content. But sometimes, the problem of steamed stuffed buns Mantou is often caused by details.

醒发的时候开裂

Cracking when waking up

醒发时候开裂主要原因是醒发湿度过低导致，或是醒发时包子馒头曝露在空气中被风干导致。

The main reason for cracking during awakening is that the humidity is too low, or the steamed buns Mantou are exposed to the air and dried.

解决这个问题的办法就是增加醒发湿度，要不用醒发箱，要不自己做一个醒发的工具，要是醒发的时候盖上块湿布，要不弄个加湿器，总而言之吧，要把醒发湿度控制在70%左右，且最好将包子馒头放在密闭的空间里醒发。

The solution to this problem is to increase the hair awakening humidity. You should not use the hair awakening box, or make a hair awakening tool yourself. If you want to cover a wet cloth or get a humidifier when you wake up, in a word, you should control the hair awakening humidity at about 70%, and it is best to put the steamed buns Mantou in a closed space to wake up.
