The tart crust does not need to be thawed in advance.
There are two parts to a tart, the crust and the liquid. The tart crust is ready-made, so when you use it, just take it out of the refrigerator without defrosting it. Because the egg tart skin will become soft during the defrosting process, after adding the tart liquid, the whole tart will become very soft, which will affect the shape of the tart, and at the same time, the egg tart will be adsorbed into the tart skin. So there is no need to defrost the tart crust.
