What is the difference between tomato sauce and tomato ketchup?
Ketchup (or catsup) is a popular condiment, usually made with ripened tomatoes. The basic ingredients in modern ketchup are tomatoes, vinegar, sugar, salt, allspice, cloves, and cinnamon. Onions, celery, and other vegetables are frequent additions. In the UK, Australia, South Africa, Malaysia, and New Zealand, their vinegar-less variant of ketchup is commonly referred to as tomato sauce or simply red sauce. Tomato sauce is a condiment made with tomatoes, and sometimes also meat, onions, basil, salt, oil, garlic and various spices. A few tomatoes are broiled, skinned and mixed with a small amount of chopped meat, onion and some salt, oil, basil and other spices. This mixture is boiled and is often passed through a sieve before it is packaged or used.
