Black bean hog hoof

The first time I ate my mother's black bean pig hoof, I fell in love with it. Pork hoofs contain abundant gelatinic proteins that increase skin resilience and resilience. This time it's a little bit of an episode. We ran out of black beans, so we went to the store. In the store, a bag of black beans was bought because they thought they were just different. Only today did we find that the black beans that we used to eat were different from the black beans that we used to eat, which were blue, called the green ones, and we've seen them again. I had to go back to the store to buy the old green beans, given the different tastes。
