Could I use milk instead of water?

This recipe garnered a whole mess of comments, mostly about the use/non-use of veal and the ensuing authenticity of the actual meatballs. I love this recipe, but I substitute additional beef and pork for the veal and have always used water for the liquid, but I would say go for the milk if you wish to use up what you have on hand. The only other advice I can offer is to dig in and get your hands messy and to add the milk in stages, not all at once, as you may not need it all. Enjoy!!

Yes, you can use milk.
