PREPARE THE SUGO DI POMODORO. This is the sauce that we are going to braise the meatballs in once they have been fried. Here is a link to the SUGO RECIPE. It can be made a day or two in advance if you don't want to cook the meatballs right away.
STORAGE. This recipe will keep in the refrigerator for 3-4 days. Cooling them and storing them for a day or two allows the flavors to meld together, so it is actually preferential, though they are delicious straight out of the sauce the day you make them. I like to eat some day of, and save the rest to enjoy later in the week with some spaghetti (Spaghetti con le Polpette).
