Kaleh joosh
Kaleh joosh is the fast, frugal soup of the Azerbaijani villages around Tabriz and of central Iran, cooked when the cupboard holds kashk, walnuts and onions. Kashk, the tangy fermented whey that gives so many Persian dishes their savoury depth, is simmered with deeply fried onions and ground walnuts, then crowned with sizzling dried mint and turmeric oil. It is eaten from a shared bowl, scooped up with torn bread rather than spoons, often on cold evenings. A common mistake is boiling the kashk hard, which can make it split and grainy; keep it at a gentle bubble. Chef's tip: taste your kashk before salting, as brands vary wildly in saltiness.
