The so-called meat fermentation is made by using the principle of fermentation. When you grind the meat, you must add a proper amount of yeast, and let it wake up for a while after filling the pot (let it ferment), so that the patties made are delicious!
You can put less flour, but not too much. You can also add some sweet potato powder. If you put too much flour, it tastes a little sticky. Don't underestimate this fermented meat. You have to do it for a long time to bring out a consistent taste. If you want to make a suggestion, you should pound it on the chopping board with the back of a knife and then stir it with chopsticks (in the same direction). Other ingredients remain the same, and the taste is slightly worse, but half a catty is ok.
