I used to work in a bakery. The reason why I made it different was that you didn't have special tools, and the materials should be proportional, so it's impossible to have more or less. Moreover, there is no stirring machine at home. There are rules for the length of stirring, and it can't be bad. Sometimes, the taste will be different if you stir for one minute more and one minute less. What's more, you use a special oven, which is different from the oven at home. Moreover, you need to add some cakes. Additives such as milk powder, of course, taste different. It is difficult to make that at home, even if the cake maker makes it at home, he can't make that taste … I hope LZ will adopt it. Typing is very hard!
