  • Roma

Roma is the classic choice for all Italian recipes and works well for tomato canning and tomato sauce. While it’s the preferred choice for canning tomato sauces, the good news is that it’s easily available. Roma tomatoes are usually 3 inches long, but you can also find larger varieties to cut down some of the prep. The common Romas aren’t too sweet, but you can choose orange Romas if you appreciate your tomato sauces a bit on the sweeter side. 

These red, plum-shaped tomatoes are another excellent choice for Italian pastes. It’s, in fact, sometimes referred to as the classic paste tomato for some obvious reasons. San Marzano is meaty, sweet and usually grows to about 2 to 3 inches in length. They’re easy to peel, have very few seeds, and are low on acidity – all the right reasons to paste them!

Big Mama is also one of the larger varieties that you can grow for pastes and sauces if you want to cut down preparation and cooking time. These plump tomatoes grow to as long as 5 inches, with up to 3 inches in width. Consider them a heftier alternative to the classic Romas.
