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.和面后靜置，這個工藝很重要，李記一般和面后要將面團在和面機里靜置1-3分鐘，讓面筋充分舒展一下，就跟人早起伸懶腰的意思差不多，和面后面團的面筋是相對緊張的，如果不充分舒展后就成型的話，很容易面筋就斷了，導致成型的時候包子饅頭開裂。

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.壓面或包制時要少放干粉，干粉太多的話，成型的時候容易開裂，在成型時要保證面團的濕度，可以用濕布蓋在面團或劑子上。這點屬于細節問題，說起來沒啥技術含量，但有的時候，包子饅頭出現的問題，往往原因就在細節上。

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.

醒發的時候開裂

Cracking when waking up

醒發時候開裂主要原因是醒發濕度過低導致，或是醒發時包子饅頭曝露在空氣中被風干導致。

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.

解決這個問題的辦法就是增加醒發濕度，要不用醒發箱，要不自己做一個醒發的工具，要是醒發的時候蓋上塊濕布，要不弄個加濕器，總而言之吧，要把醒發濕度控制在70%左右，且最好將包子饅頭放在密閉的空間里醒發。

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.
