What's the best tomato variety for canning: Roma Tomatoes - Prized for its use in tomato paste and sauces since its introduction in 1955, Roma Tomatoes produce a large harvest of thick-walled, meaty, bright red, egg-shaped tomatoes about 3 inches long and with few seeds. This tomato is not juicy. This is not a slicing tomato. Instead, the flesh is thick and drier so that it will cook down into a thick sauce. Cooking intensifies flavor, too. If you can tomatoes, make your own spaghetti sauce, or like to chop a tomato into an omelet, this is a great choice. It's not too juicy in the pan compared to slicing tomatoes. The fruit freezes well for later cooking, too.
