the Yuan Dynasty
Kublai Khan ate instant-boiled mutton when he got cold feet.
The most popular saying is that the origin of instant-boiled mutton is related to Kublai Khan in Yuan Shizu.
According to legend, Kublai Khan led the army south. One day, when people were hungry, they suddenly remembered the dish of their hometown-stewed mutton, and immediately ordered their men to kill the sheep and burn the fire. Just when the cook slaughtered the sheep and cut the meat, he found the enemy's situation. Knowing that he wanted mutton, the chef used his quick wits. He cut off more than ten thin pieces of meat with a flying knife and scalded them in boiling water several times. When the color of the meat changed, he immediately fished it into a bowl and sprinkled it with fine salt. Kublai Khan ate a few bowls, turned over and mounted the horse to meet the enemy, and won a great victory.
When preparing for the celebration dinner, Kublai Khan specially ordered mutton slices. The chef chooses the tender meat of the sheep, cuts it into thin slices, and matches it with various seasonings. After eating, the generals were full of praise. The chef hurried forward and said, "This dish has no name yet. Please give it a name. " Kublai Khan smiled and replied: "I think this is called' instant-boiled mutton'!"
