Roma tomatoes, also known as plum tomatoes, are a popular variety in culinary uses due to their firm flesh, low moisture content, and relatively low seed count. They have an elongated, oval shape and vibrant red color when ripe. Known for their mildly sweet and tangy flavor, Roma tomatoes are ideal for sauces, salsas, and canning, as their thick walls hold up well to cooking and offer a concentrated tomato flavor. Their dense texture also makes them suitable for roasting and drying, as they retain their shape and enhance in sweetness when heat is applied.
