Plum tomatoes are oval-shaped tomatoes with firm, meaty flesh, relatively few seeds, and less moisture than many round tomato varieties. Roma tomatoes are one of the most common types of plum tomato, although other varieties are also included in this category. Plum tomatoes typically have a balanced flavor that is mildly sweet, tangy, and slightly acidic. Their dense texture and lower water content make them especially well suited for sauces, soups, roasting, grilling, and other cooked preparations because they break down into a thick, flavorful consistency without becoming excessively watery.
