Khoresh-e Gharch

Khoresh is the broad Persian category of slow-cooked stews eaten over rice, and within it the mushroom version is a comparatively recent and casual member. Cultivated button mushrooms only became widely available in Iran in the modern era, so unlike the herb stews traced to pre-Islamic times this dish has no deep documented history; it sits among the everyday tomato-based khoreshes alongside Khoresh-e Gheimeh's lighter cousins. Saffron, by contrast, is the oldest Persian flavoring of all, cultivated in Khorasan for well over a thousand years, and it does the aromatic work here that herbs do elsewhere.

Soft chunks of chicken and slippery slices of mushroom in a loose, saffron-gold sauce that is more a flavored broth than a thick gravy. The mushrooms give up their water and take on the savor of the pot; the chicken pulls easily from the bone. It is mild — no sour bite, no bitter herb edge — clean and warm, the saffron lifting an otherwise simple braise. Spooned over white or saffron rice, the sauce soaks in.

The mushrooms are sauteed first, on their own or after the onion, to drive off their water before the liquid goes in; added raw to the sauce they would dilute it and steam grey rather than browning. The saffron is bloomed — ground and steeped in a little hot water — so its water-soluble pigment and aroma disperse evenly through the sauce instead of clumping. The chicken simmers only until just tender; because there are no tough herbs or beans to soften, the whole stew comes together far faster than a Ghormeh Sabzi.
