Chicken with Verjuice, Saffron, Medieval Spices, and Mint

Verjuice (see Verjuice) was popular in medieval cooking as a source of acidity and is used more and more in modern cooking. The saffron, of course, is typically medieval, while the mint and sugar are typical of the Renaissance. This dish is quite sour, also typically medieval, but you can attenuate it by adding cream.
