Can a biscuit be frozen?
it is impossible, he will just lose half of his taste
Not worth it, all the charm of the taste will disappear if you freeze it for a long time, it seems to me. But if it bakes, freeze it, and then make a dessert with it: cut it into pieces, put it in a bowl, soak it with cream, sour cream, for example, it will be nice, especially if you add berries or jam. So with a certain imagination it will be nice.
Of course, I have not tried it, but I watch many master classes from great chefs, they almost all freeze before the final coating, no matter they have mousse cakes or biscuits. So I think you can - otherwise they would not do that.
