The fastest and easiest way to roll meatballs is to use an ice cream scoop. I have several sizes of scoops, depending on how large I want the meatballs. For these meatballs, I use my 2-tablespoon scoop. I dunk the scoop in a glass of water, which help the meatball mixture to release, scrap the top of the scoop across the edge of the bowl, and pop the meat into my palm. A quick roll between my palms makes sure I have even-sized meatballs that will cook at the same rate.
