Sindhi biryani gets part of its tang from a few dried plums (aloo bukhara) tucked into the pot, along with yogurt and tomato — a fruity, sour note that marks out the Sindhi style.
Basmati rice is layered with meat, potatoes, tomatoes, yogurt and a heavy hand of red chili, the layers slow-cooked together so the rice soaks up the tangy, spiced gravy. Sindh's roadside dhabas and city biryani houses ladle it out by the plate with a wedge of lime and raita.
