2. Wrap the egg tart with plastic wrap or keep it in a fresh-keeping box. Because egg tart is a kind of baked food, if it is not placed in a well-sealed space, it will easily absorb some moisture in the air, resulting in the skin of egg tart becoming very soft, not crisp. Moreover, putting the egg tart in the fresh-keeping box can also make the egg tart not easy to rot and deteriorate, and will not react with some substances in the air, which can well preserve the fragrance of the egg tart.
If the egg tart is raw, it can also be kept in the refrigerator, but remember that the egg tart water and the egg tart skin should be kept separately. Especially egg tart skins, can be preserved for a long time. In general, if you don't take it out halfway, you can keep it for about a week and it won't go bad. But for egg tart liquid, it is not easy to preserve because it contains eggs and milk. So you can put the egg tart liquid at the lowest place and keep it fresh and sealed, which will keep the egg tart liquid for about three days. If you haven't finished eating for more than three days, you must dispose of it in time, otherwise it will breed a lot of bacteria.
