1. Lowering the recipe temperature and prolonging the baking time can make the shelf life of the souffle relatively longer, and at the same time ensure that the souffle will not soften quickly;
2. seal the souffle with a sealing machine and put it in a cool and dry place, which can appropriately extend the storage time, but it is best to eat it within one week;
If you can't use preservatives at home, buy some desiccants and put them in the box in the souffle. Ensuring the drying of souffle can prolong the shelf life;
It can be extended for a period of time in the cold room, but it is best to eat it within one month. If you want to give it away, you can use the method of adding dry ice to the incubator. Dry ice won't melt so quickly, so you can take it out in time to eat.

6. The bought bean paste stuffing is safer than the homemade one, and the water content is much lower than that fried at home.
