What is Gheymeh?

Gheymeh is a khoresh built on yellow split peas, small cubes of lamb or beef, tomato, turmeric, and — crucially — dried limes (limu omani) that steep in the pot and give the whole thing a sour, faintly bitter backbone that separates real gheymeh from a plain meat stew. The split peas cook down until they're tender but still hold their shape, thickening the sauce without dissolving. It simmers low for a couple of hours until the oil rises to the surface in an orange slick that older Iranians consider a sign of a stew done properly. Served over white rice, it is one of the two or three stews that anchor the Persian weeknight rotation.

The signature move, the thing that makes people's eyes go a little soft, is the topping: thin matchsticks of potato fried crisp and piled over the stew right before serving, so they stay crunchy against the soft peas underneath. Some cooks add a scatter of them into the stew too. There are grander variations for special occasions — gheymeh bademjan folds in fried eggplant, and the elaborate Qazvini gheymeh nesar, a wedding dish, is showered with barberries, slivered almonds, pistachios, and orange peel until it barely looks like the humble weeknight stew it started as. The spice base is often a pinch of advieh (the Persian warm-spice blend), and the dried limes are pierced and dropped in whole so they can be fished out or left to be squeezed by whoever loves them most. Gheymeh is also the definitive nazri food — cooked in enormous vats and given away during Muharram and at memorial gatherings (called by the shortened name gheymeh nazri), ladled to strangers as an act of charity and remembrance. Which means for many Iranians the smell of gheymeh is inseparable from crowds, black clothing, steam rising off street-side cauldrons, and the particular generosity of grief.
