So, what's in a name? Variations such as 'catsup', 'catchup',
'katsup', and 'ketchup' abounded in the early days of the condiment.
In 1690 the word 'catchup' appeared in print in reference to this
sauce, and in 1711 'ketchup'. The 1727 edition of The Compleat Housewife2
included a recipe for 'English Katchop'3. Catsup and catchup are
acceptable spellings, but most cookery books (and normal people)
spell it ketchup. However, the name would come into play much later
in ketchup's history.
