What is mustard?

Mustard is one of the 14 allergens that must be declared in the UK and the EU, and the Gulf standard GSO 9 lists it too. It is not on the US list, so an imported American product can contain it without naming it in the way a British one would. In a Gulf supermarket, both sit on the same shelf.
