Anar Bij

Anar bij ("pomegranate seed/grain" in the local Gilaki sense) is a folk dish of Gilan province, the humid lowland between the Alborz mountains and the Caspian Sea; its precise origin is undocumented, as with most of the region's village cooking. The Caspian littoral is one of Iran's oldest walnut- and pomegranate-growing zones, and its near-Mediterranean climate of heavy rain and dense greenery supports a cooking vocabulary — sour fruit, raw garlic, walnut, a fistful of fresh herbs, fish and fowl — that sits apart from the drier, sweeter stew tradition of the Persian interior and leans toward the Caucasus. Within that vocabulary anar bij is the meatball cousin of fesenjan: the duck or chicken is swapped for small kufteh, and the sauce is pushed greener and more sour with chopped herbs and verjuice. Gilani cooks favor a black, sour pomegranate paste (rob-e anar) over the sweet kind, which is what keeps the dish tart-forward rather than rich.

Small browned meatballs sit in a thick, grain-flecked green-brown sauce, glossed dark by walnut oil and pomegranate. The first taste is a clean, puckering sourness, then the herbs come through grassy and savory, and only underneath does the ground walnut settle in — earthy and slowly filling. It is lighter on the tongue than a Tehrani fesenjan and far greener-tasting, the tartness kept sharp rather than candied. Spooned over white rice, the sauce stains the grains the color of wet bark.

The dish runs on a deliberate fight between walnut and acid. Walnuts carry their bitterness and dry, puckering astringency in the thin brown pellicle, which is dense in ellagitannins that bind to the proteins in saliva; left alone in a long simmer the ground nuts would turn the sauce harsh and chalky. The sour pomegranate paste and verjuice answer this two ways: their fruit acids (citric and malic in pomegranate, tartaric and malic in verjuice) brighten the whole pot, and the acidity helps keep the tannins in suspension and folds in the dissolving walnut fat so the sauce reads round and glossy rather than bitter. The herbs are chopped fine and sweated in oil first to drive off their raw grassy note and concentrate their aroma before the liquid goes in. The meatballs are bound tight with grated onion (and sometimes a little rice flour) and browned before they are dropped into the sauce, which sets their surface protein so they hold their shape through the slow cook instead of crumbling into the stew.
