Royal Icing is the lace dress of frosting—beautiful, delicate, and capable of holding a grudge. It’s made from egg whites and powdered sugar, and it dries harder than a physics exam. This is the stuff you see on gingerbread houses that look too perfect to eat.
Fun fact: royal icing was originally used to glue cakes together before modern cake stands existed. It’s also surprisingly strong—I once saw a gingerbread shed survive a light drizzle. You can’t taste it without risking a tooth, but it makes cookies that look like Renaissance art.
