Japanese people like this kind of food.
It is called street food, izakaya food.
It takes 4-5 hours to get soft. Then add daion radish and other vegetables.
It is good for your skin because of rich gelatin.
I tasted and felt OK. It is too heavy to eat for me.
I prefer OX tail or neck.
Would you like to try? It is available next 3-4days.
