I don't know what kind of tofu balls you are talking about. We have several kinds here, one is water tofu balls, the other is fried tofu balls, and the other is tofu and meat kneaded into a ball. Water tofu balls are the most difficult to make and cook. Be gentle with your hands, or you will crush the tofu. Pay attention when frying. Fried tofu is easy. Just tear the fried tofu into small mouths and put the meat in. As for meatballs made of meat, that kind of tofu is harder than ordinary ones. Just knead it directly with the meat and adjust the taste!
