According to the idea, you need to partially or completely remove the skin from the legs, the first is a lot of fat, the second is that the broth will become cloudy. But I leave it on one, then remove it when slicing. Here, as you can see in the photo, the broth turned out to be light. So, rinse the ham well, put it in a saucepan, cover with water and bring to a boil. Drain the water, rinse the legs and fill them with fresh water again. As soon as it boils, if foam appears, we remove it, but usually it is not enough, but for the transparency of the broth we try to remove everything.
