Sumac

Rhus coriaria · Anacardiaceae (cashew family)

Sumac
Ground dried berries with a deep red-purple colour and a clean, lemony sourness — the Middle Eastern lemon, and the way to make a dish tart without making it wet. That is the whole case for keeping it: sumac gives you acidity in a dry rub, on a grill, over a salad, where a squeeze of lemon would soften everything it touched. Three products carry it.

How to use it

Over fattoush, hummus and grilled meat. In za'atar with thyme and sesame. Rubbed on chicken or lamb before roasting. Sprinkled over sliced onions beside a kebab, the Turkish way. Over eggs, yogurt, roasted vegetables, fish. Use it where you want sourness and not moisture.

With food

Onion. Chicken and lamb. Yogurt and labneh. Chickpeas. Cucumber and tomato. Olive oil and flatbread. Eggs. Pine nuts.

With spices

Thyme and sesame — za'atar. Allspice and saffron, in musakhan. Black pepper. Cumin. Coriander seed. Mint.

With tea

Not a tea ingredient, though staghorn sumac cones are steeped on their own as a tart North American drink.

Its story

Where it comes from

Rhus coriaria is native to southern Europe and western Asia — the eastern Mediterranean, Crimea, the Caucasus and northern Iran — and naturalised around the Mediterranean; it is also called Sicilian sumac and tanner's sumach. Turkey is the most common trade origin but our lot is unconfirmed. Its North American cousin, staghorn sumac, grows wild across southeastern Canada, and its red cones are steeped into a tart sumac-ade.

What happened

The name is a colour: through Old French and Medieval Latin from Arabic summāq, from Syriac summāqa, meaning red. Romans used sumac for sourness before lemons reached Europe. The oldest surviving Arabic cookbook — the tenth-century Kitab al-Tabikh, compiled by Ibn Sayyar al-Warraq from the recipes of the Abbasid courts of Baghdad — has an entire section of sumac stews, summaqiyya, and one variation, haruniyya, carries the name of Harun al-Rashid, the caliph of the Thousand and One Nights. From the thirteenth to the fifteenth century sumac was used widely in wealthy European kitchens too. In Palestine it makes musakhan, often considered the national dish, traditionally cooked in the olive-harvest season; in April 2010 forty cooks at Arura made one four metres across and weighing 1,350 kg, which went into Guinness World Records.
