Ketchup is a popular condiment made primarily from tomatoes, vinegar, sugar, and various spices. It is commonly used to enhance the flavor of foods such as fries, burgers, and hot dogs. The sweet and tangy taste of ketchup makes it a favorite for many, and it is often found in households and restaurants around the world. Originally derived from a fermented fish sauce from Southeast Asia, ketchup has evolved into the tomato-based version we know today. Its versatility allows it to be used in a variety of dishes, making it a staple in many cuisines. Tomatoes are the key ingredient, providing both flavor and color.
