I enjoy ketchup more than the average person. Made with tomatoes and vinegar, this ubiquitous red sauce is my condiment of choice for a wide variety of dining situations. Sweet and tangy, it's perfect for eating with french fries and burgers, of course, but you might not realize how good it is incorporated into other dishes. Its unique sweet and savory nature makes it a bit of a dynamo that way. No wonder this addictive table staple of households and restaurants is so beloved.
