San Marzano tomato tomatoes sold commercially are grown in Italy, though they are produced commercially in smaller quantities in other countries. Because of San Marzano's premium pricing, there is an ongoing battle against fraudulent product. On November 22, 2010, the Italian carabinieri confiscated 1,470 tons of canned tomatoes worth €1.2 million of improperly labeled product. San Marzano tomatoes, along with Roma tomatoes, have been designated as the only tomatoes that can be used for Vera Pizza Napoletana (True Neapolitan Pizza). San Marzano tomatoes originate from the small town of San Marzano sul Sarno, near Naples, Italy, and were first grown in volcanic soil
Plum tomato Plum tomato A plum tomato, also known as a processing tomato or paste tomato, is a type of tomato bred for sauce and packing purposes. They are generally oval or cylindrical in shape, with significantly fewer locules (seed compartments) than standard round tomatoes (usually only two) and a generally higher solid content, making them more suitable for processing. Plum tomatoes are also sometimes favored by cooks for use during the tomato off-season, as they are generally considered more amenable to handling and are therefore available in a state closer to ripe than other supermarket tomatoes.
