I remember as a child being taken by my grandfather to the now sadly defunct London Steak House, and being especially impressed by a fawning waiter, no doubt in an egg stained maroon mess jacket, offering me a suave choice of English, German or French mustard. And, when you're ten years old, that's a big deal.
Colman's of Norwich make one of the most famous brands of mustard. Founded by Jeremiah Colman in 1814, it's a classic English mustard with a deep yellow colour, tangy taste and powerful kick. Connoisseurs of the brand reckon that the best version is Colman's mustard powder, which you mix up with water, and then leave for about twenty minutes to bring out the oils and for the full, robust flavour to develop.
I'm also fond of the classic all- American French's Mustard, which has as about as much to do with France as the Empire State Building. Created in 1904 by Robert Timothy French, this is a creamy, bland mustard, which is similar in some ways, to milder German varieties.
