Notes
Note 1: Sausage
You can use an additional half pound of ground sausage if you like more meat and less sauce. For a spicier sauce, use hot Italian sausage.
Note 2: Crushed Tomatoes
Choose high-quality San Marzano Italian tomatoes for the best sauce. We used Cento brand.
Note 3: Sugar
You may need to add more sugar to taste, depending on the crushed tomatoes you choose.
Note 4: Leftovers
Allow leftovers to cool to room temperature. Transfer to an airtight container and store in the refrigerator for 3-4 days or in the freezer for up to four months.
