Many consumers ignorantly believe that all tomato and sugar based condiments are created equally. However, there are a myriad of differences that can be found between ketchup and catsup. Ketchup was invented in the early 1940s by Hungarian tomato farmers as a way of preserving their tomato jam which was often used on their native staples of bratwurst or linguini. Catsup originated in Vietnam in the early 1910s as a type of tomato pudding served room temperature in a small dish often eaten with bread. Both products eventually made their way into US markets and much like Pepsi and Coke, have very devout followings.
