The dipping sauce of gold and silver steamed bread is called condensed milk sauce. Personally, I think the golden steamed bread is fried and the silver steamed bread is steamed. Both are the same food. If you prefer sweets, dip it in condensed milk sauce, which tastes quite good. If you like to eat sweet and sour, you can also dip in some ketchup.

Brief introduction to condensed milk history

1866, American Becky also established a condensed milk factory to produce sweetened condensed milk. Meinberg, a technician from Baiji Company, also studied a new method to produce condensed milk. Before that, people didn't know the real reason for the deterioration of fresh milk. 1857, L. Pasteur, a famous French biologist and chemist, first discovered that food corruption was caused by microbial reproduction.

Pasteur invented the heat sterilization of wine and beer in 1865 and 1873 respectively. Inspired by this, Meinberg invented a new milk concentration method in 1884. After canned condensed milk, it was sterilized at high temperature to produce sugar-free condensed milk which can be preserved for a long time.
