Sumac (Somagh): What It Tastes Like and When to Reach For It

What does sumac actually taste like?

Sour, but not the way a lime is sour. Sumac — somagh — tastes of dried red fruit, somewhere between cranberry and pomegranate, and the sourness runs along the sides of the tongue and then dries the mouth instead of making it water. It grips rather than stings. There is a faint savoury edge behind the fruit too, so a heavy shake reads as seasoning and not only as acid.

That drying quality is the part nobody explains. It is the same sensation as strong tea or grape skin, and it is why sumac suits food straight off a fire. Our guide to the Persian sour pantry lists sumac beside lime and pickles; this piece is about how it differs from them in the mouth.

How is sumac different from a squeeze of fresh lime?

Fresh lime is wet, bright and loud. It carries citrus oil, so half of what you notice is smell. The acid is clean and sharp, it lands at once, and it fades fast. It also adds liquid, which matters more than people expect: squeeze enough over a bowl and you have thinned it.

Sumac adds no liquid at all. There is almost no aroma either: a good jar smells faintly fruity, not citrus. The sourness is slower to arrive, rounder, and it stays put. Lime changes the liquid in a dish. Sumac changes the surface.

Is sumac just a dry version of dried lime?

No, and this is the pair people confuse most: both are dry, both are sour, and Persian recipes list them in the same breath. They do opposite jobs.

Dried lime needs heat and time; it is a decision the cook makes long before anyone sits down. Sumac is the opposite. Heat dulls it, so it comes out at the end. Put it in a pot at the start and you get muddy colour and very little sourness.

Whole berries or ready-ground: what changes?

Both turn up in Dubai, and they behave differently.

• Whole berries. Small, dark and dried, like hard little currants, sold loose by weight. The flavour sits in the fleshy coat around the seed, and the seed itself carries little of it, so crush them in a mortar or spice mill and sieve out the grit. Less surface is exposed, so the punch survives better.
• Ready-ground. What most jars hold: even, consistent, no work. It loses its edge sooner, and it is the form most likely to have something else in it.
• Steeped and strained. The forgotten option. Soak whole berries and strain, and you have a sour red liquid to brush over grilled meat or stir into a dressing — sourness without the grit.

Why does a jar of ground sumac sometimes taste mostly of salt?

Because a great deal of ground sumac is blended with salt. Some producers add a little to keep it loose, some add a lot, and a few add citric acid as well, which makes a jar sharper and flatter at once. It is not usually hidden: the ingredient list says so. It is just rarely read.

So taste before you shake: tip a pinch into your palm and try it. If salt lands first and sourness second, use that jar as a seasoning and take the salt out of the food elsewhere. If sourness lands first and the fruit follows, you have the real thing and can be generous. A label reading sumac and nothing else is what to look for; whole berries settle it outright.

How do you tell a tired jar from a good one?

Colour first, then smell, then taste. Live sumac is a dark purple-red, close to dried cranberry, and clumps very slightly rather than pouring like dust, because the ground fruit still carries a little of its own oil. A tired jar has faded to pale brick or brown-orange and runs loose and powdery.

Then smell it. A faint dried-fruit sweetness under the sourness means it still has something to give; nothing at all, or the smell of the cupboard, means it does not. Tired sumac tastes thin and dusty, flatly sour with no fruit behind it. It will not spoil anything, it simply will not do the job, and extra shaking does not bring it back. Keep it in a sealed jar, out of the light, and buy a size you will get through. Iranian and Middle Eastern grocers around Dubai usually carry both forms.

What does sumac do on grilled fat that a lemon wedge cannot?

This is where sumac is not just an option but the better tool. Meat off the coals — kabab koobideh, shishlik, jigar — reaches the plate with hot fat on its surface. Squeeze a wedge over that and most of the juice runs off, pools under the meat and soaks the bread. The middle of the bite never meets the acid; the plate just gets wet.

Sumac lands on the fat and stays there. Nothing runs, so the sourness ends up where the richness is, which is the only place it was needed. Dust it on once the meat has had a moment off the skewer and it clings.

Two other places it beats juice outright: raw onion, sliced thin and tossed with sumac, loses its aggression and takes a pink edge; and plain rice, where lime leaves wet patches and a dusting spreads evenly.

Where does sumac not belong?

Four places, roughly.

• In a long-simmered pot. Time and heat take the fruit out of it and leave a muddy colour behind.
• Stirred into broth. It does not dissolve. It floats, clumps, and settles as grit at the bottom of the bowl. A rich Persian broth wants a wet acid instead — lime, garlic and cinnamon are the usual finish for a bowl of kalle pache, and none of that work belongs to a dry powder.
• On delicate, milky or sweet food. The drying grip flattens gentle flavours. On plain yoghurt or a soft omelette it reads as dust.
• On a plate that is already sour. Heavy torshi, a vinegary salad, plenty of lime already squeezed in — pile sumac on top and the acids stop being interesting and simply become sour.

One rule covers the rest: sumac is a finishing dust, not a coating. Shake, taste, shake again if the food asks. Too much at once and the whole plate tastes chalky.

Kalle pache itself is not a sumac dish. At Shaun the Sheep on Jumeira Street in Jumeirah 1 the pot runs the long way, around fourteen hours.
