What is catchup?

Ketchup (sometimes spelled catchup) is a condiment that is usually served with foods like hamburgers, hot dogs, and french fries. It is made primarily from tomatoes, vinegar, sugar, and various spices and seasonings. The origins of ketchup can be traced back to China, where a similar sauce was made from fermented fish and soybeans. Ketchup became popular in the United States in the 1800s as a way to make tomatoes more palatable, as many people did not like the taste of raw tomatoes. Today, there are many different varieties of ketchup available, including those made with different types of tomatoes, sweeteners, and spices. Ketchup is a popular condiment all over the world and is considered a staple in many households.
