Do you need rotten eggs to make cakes? Why don't you believe that you can't make a bad cake without your rotten eggs

Trough cake is a common name for cakes in old Beijing. Trough cakes can be made without eggs, but they are made like steamed bread with flour, which tastes much better and is nutritious with eggs. Therefore, as the saying goes, you can't make a cake without eggs, or you don't believe that you can't make a cake without eggs. Rotten eggs are absolutely not allowed to make cakes. This is a derogatory remark, and adding a dirty word is even more insulting.
