More about "catsup", according to the Global Gourmet's Culinary Sleuth:

"When Heinz introduced commercial ketchup to American kitchens it became so popular that other manufacturers rushed to catch-up to the ketchup craze. Soon there were Ketchup, Catsup, Catchup, Katsup, Catsip, Cotsup, Kotchup, Kitsip, Catsoup, Katshoup, Katsock, Cackchop, Cornchop, Cotpock, Kotpock, Kutpuck, Kutchpuck and Cutchpuck. All were tomato based and bottled and vied to become a household word. Only 3 major brands remained to steal the spotlight...Heinz Ketchup, Del Monte Catsup, and Hunts, who could not decide on a spelling and bottled under the names Hunts Catsup (east of the Mississippi), Hunts Ketchup (west of the Mississippi), and Hunts Tomato Cornchops (in Iowa only). In the 1980's ketchup was declared a vegetable by the government for school lunch menus. Suddenly Del Monte's Catsup, because of its spelling, was not on the approved list. Shortly afterward Del Monte changed the product's name to Del Monte Ketchup. So ketchup it is."
