Sumac

In a nutshell

Sumac is a tart spice from dried berries, adding lemony flavor and color.

Sumac is a deep red-purple spice made from the dried, ground berries of a Middle Eastern shrub. It tastes bright and tangy like lemon, with a soft fruity sweetness, a little earthiness and none of citrus's sharp bitterness.

Cooks love it because it adds sourness without liquid. Sprinkled over hummus, salads, grilled meat or eggs, it brightens and colours the dish at once. It is a key part of za'atar and the star of fattoush and sumac onions.

Aroma: tangy, citrusy

Good to know

Origin: Middle East

Forms: powder

Season: Available year-round dried; the berries are harvested in late summer and autumn.

Nutrition: Used in small sprinkles, so it adds flavour and colour rather than nutrition.

Storage: Keep sumac in an airtight jar in a cool, dark, dry cupboard, away from the stove. It holds its colour and tang for about 6 months to a year before slowly fading. When it turns brownish and smells of little, its sourness has dropped and it is time to replace it. You can freeze it in a sealed jar to stretch its life, letting it warm up before opening so moisture does not clump it.

How to use sumac

Seasoning Meats

Sprinkle sumac on meats before grilling; acidity balances fatty cuts.

Elevating Dressings

Mix into dressings; sumac's tartness sharpens vinaigrettes.

The science of sumac

Sumac's sourness comes mostly from malic acid, the same acid that makes green apples tart, along with citric and other fruit acids. Because the acid is dry, it brightens food without thinning dressings or wetting crisp things.
The berries' deep red colour comes from anthocyanins, water-soluble pigments. Soak sumac in a little water or rub it into sliced onions and the juice turns vivid pink-red.
Sumac also contains tannins, which give a slight drying pucker. That astringency helps it cut through fatty lamb, oily fish and rich dips.
Its fruity aroma compounds are delicate and fade with long, high heat. Add most of it at the end, or rub it on meat just before grilling, for the brightest taste.

How to choose sumac

Good sumac is a vibrant brick red or burgundy, slightly moist and clumpy, and smells fruity and tart. Dull brown sumac is old or cut with fillers. Some blends include salt, so check the label and taste before seasoning further.

Sumac: questions

What does sumac taste like?

Sumac tastes tangy and lemony with a gentle fruity sweetness, but it is softer than lemon juice and not bitter. It also has a mild earthy note and a slight pucker from its tannins.

Is sumac poisonous?

Culinary sumac comes from Rhus coriaria and related red-berried species, and it is safe to eat. Poison sumac is a different plant with white berries and is not sold as a spice.

How do you use sumac?

Sprinkle it over hummus, labneh, eggs, salads and roasted vegetables, rub it on chicken or lamb before grilling, or toss thinly sliced red onion with sumac and salt for a quick tangy topping.

What is the difference between sumac and za'atar?

Sumac is a single spice made from dried berries. Za'atar is a blend that usually contains sumac along with dried thyme or oregano, toasted sesame seeds and salt.

Can I cook with sumac or only sprinkle it?

You can do both, but its fruity aroma fades with long heat. Use some in rubs or marinades and save a final pinch for the end to keep the colour and tang vivid.
