Roma tomatoes, also known as plum tomatoes, are medium-sized, oval-shaped tomatoes with firm flesh, relatively few seeds, and less moisture than many round tomato varieties. They typically have bright red skin and a dense, meaty interior, making them especially well suited for cooking. Roma tomatoes have a mildly sweet, tangy, and slightly acidic flavor that becomes richer and more concentrated when cooked. Their lower water content allows them to break down into thick sauces and hold their shape well in roasted, grilled, and baked dishes.
