If you want to open a breakfast shop alone, then this breakfast variety should do these two things. First, it can be produced in batches, and second, it can be preserved for half a day, and it can also be kept fresh. For example, porridge, you can burn a large pot at a time, then put it in a thermos bucket and sell it in the morning. So I can cook porridge and sell it the next morning. There are also big steamed buns, such as big vegetable buns and big meat buns, which can be made first and then put in, like, a foam box for holding fruit, and then, at night, they can be made and sold the next morning.
Then the allocation of time is to purchase in the morning, then simply clean it, prepare it in the afternoon, make it officially in the evening and sell it the next morning. In this way, one person can make excellent sales several times and purchase raw materials. So one person's breakfast shop is ok, but if you make fried dough sticks, you can't, because the fried dough sticks have to be mixed with flour and fried, and then you have to serve porridge to people, so you can't have time alone. It is possible to make big steamed buns with porridge.
