Home made mince is usually very lean as we tend to cut all the fat off but if you can bring yourself to leave some in, it will be a lot more moist. Sounds like doing 1/2 quantities of the meat is the way to go VHJ and it will be interesting if you or someone else could compare the moistness of this recipe with bought mince. Did you make some sort of sauce to go with them or did you serve them as a hamburger?
