Hello! Because you used to make your own tarts, and because you saw semi-finished tarts for sale, you felt tired of making your own tarts, and because you saw other people (bakery stores) selling semi-finished tarts in large quantities (because they processed them mechanically), you inevitably thought that there was a difference between your own and other people's tarts, and you even suspected that your own tarts were not as good as other people's tarts. As for whether the egg tart crust is halal or not, it is hard to say: egg tart eaters will not care so much, as long as there is a halal flavor; egg tart crust should be filled with lard in order to adhere and have a strong flavor, but the portion should be moderate. Please refer to! Thank you
