Note: After revisiting this, in regards to garlic, keep in mind the size of the cloves--the 8 I have represented can be from 5-9, depending on the individual clove size.
I bring this up since I just cranked out 48 meatballs for a holiday party for tomorrow.... the 48 was with 3lb of meat, in golfball size.
Trust me, this recipe is my pride and joy and has been in my family for 4 generations, although my version is the best.
