Tomato ketchup

This is only one of many ketchups or ‘catsups’ that were once the stock-in-trade of Victorian cooks, who used them liberally - all too liberally - to improve their sauces and gravies. But while mushroom ketchup and walnut ketchup have gone the way of the comfortable railway waiting-room, where they used to be dispensed from the buffet, tomato ketchup has become the one essential sauce with all children and quite a number of adults too.
