Dorne remained independent for a full two centuries after the Targaryen Conquest, and only came under the authority of the Iron Throne one hundred years ago through peaceful marriage-alliance. Thus it is not quite as interconnected through trade as the other kingdoms are. Moreover, due to the imposing at the base of the Dorne peninsula, and the forbidding deserts of central Dorne, overland transport to and from Dorne is fairly difficult, so there are no major roads linking it to the other kingdoms. However, a considerable amount of trade still occurs by sea, as well as some land-based trade using caravans across the desert. The dry deserts of Dorne might not produce large quantities of food to export, however, the irrigated river-valleys allow for a fair amount of agriculture. Because Dorne is so climatically and ecologically different from the rest of Westeros, exotic crops grow there which don't grow in the rest of the continent, particularly citrus fruits and olives, as well as spices (both grown locally and obtained from the nearby ). The lemons for 's prized lemon cakes originate in Dorne. Because so many exotic foodstuffs are available, Dornish wine is very flavorful and different from the wines of the Reach. Noblemen across the Seven Kingdoms who claim a refined palate enjoy the exotic taste of sour Dornish red wine. Thus while Dorne doesn't produce much in the way of basic foodstuffs, it does produce many exotic luxury foods (i.e. citrus fruits) which are not produced anywhere else in the realm - which means that Dorne still conducts brisk trade with the rest of the Seven Kingdoms in exchange for its unique products..
