Roma Tomato, also known as a pear or paste tomato, is widely grown throughout Mexico and the U.S.. Its distinct and compact oval shape is available in both yellow and red and it is known for its firmness. It has fewer seeds and less juice than other tomatoes and is often used in tomato based sauces due to its full flavor. Ripe tomatoes should be stored at room temperature and never refrigerated. Chilling a tomato not only changes the texture from firm to pulpy, it also changes the flavor. Refrigeration causes the sugars to convert to starch, reducing the flavor by 30% or more. Tomatoes are an excellent source of potassium, and Vitamins C and A.
