" Wienrich and Boettcher were, naturally, foreigners, and according to Ankh-Morpork's Guild of Confectioners they did not understand the peculiarities of the city's tastebuds.
Ankh-Morpork people, said the Guild, were hearty, no-nonsense folk who did not want chocolate that was stuffed with cocoa liquor, and were certainly not like effete la-di-dah foreigners who wanted cream in everything. In fact they actually preferred chocolate made mostly from milk, sugar, suet, hooves, lips, miscellaneous squeezings, rat droppings, plaster, flies, tallow, bits of tree, hair, lint, spiders and powdered cocoa husks. This meant that according to the food standards of the great chocolate centres in Borogravia and Quirm, Ankh-Morpork chocolate was formally classed as 'cheese' and only escaped, through being the wrong colour, being defined as 'tile grout'.
