Rationales and Disclaimers

 * Most of this article, outside of common ingredients, will be fanon as there isn't much known about specific provincial diets. Stormwind is a bit of an anomaly, having as much in-game detail as it does.
 * This article is deliberately set prior to the Worgen curse except where otherwise noted.
 * No boar are ever seen in Gilneas, but they're referenced in the cuisine anyway. My hypothesis? They ate the bloody lot in the famine.
 * We never see a cow, either - and the lots'o meat pie's flavour text, though meant to be a joke, actually suggests something. There's no beef in the damn thing. No cows, or very few - so Gilnean white is likely sheep's milk cheese.
 * Given the famine and the general hunger following it, it's probably safe to assume a diet heavy in grains and legumes, with much of the meat coming in the form of salt or smoked fish.
