Pul biber is Turkish red pepper flakes: mild, fruity red peppers that are dried, seeded and crushed into coarse, slightly oily flakes. The name means "flake pepper". It comes from Gaziantep, Kahramanmaraş and Şanlıurfa in southeastern Turkey, and English recipes usually call it Aleppo pepper, its close relative from across the border.
This guide explains how the two are connected, how hot pul biber really is, how it compares with Urfa pepper (isot), Maraş pepper, ordinary chili flakes and paprika, what to use when a recipe asks for Aleppo pepper and you have none, and how Turkish kitchens actually use it. We ship pul biber from Turkey every week, so the buying advice comes from the jar, not from a search result.
How is pul biber made?
The peppers are picked fully red at the end of summer, from August into October. They are split, seeded and spread out to dry in the sun, on flat rooftops or on cloths laid over the ground, or today often in drying rooms. Once dry, they are crushed rather than ground, so the flakes stay coarse.
Many producers then rub in a little oil and a pinch of salt. That keeps the colour bright and the flakes soft, and it is why good pul biber looks faintly glossy and clumps a little in the jar. Urfa pepper, isot, goes one step further: the peppers dry in the sun by day and are wrapped up at night so they sweat, and the cycle repeats for several days until the flesh turns almost black.
Our Gaziantep pul biber and our isot are both packed by Namlı Gurme, and the zahter breakfast blend comes from Tahmis, the old coffee house of Gaziantep. All three ship to you from Turkey.
Is pul biber the same as Aleppo pepper?
Almost. They are the same kind of pepper, grown on the same stretch of land and processed the same way. Aleppo pepper takes its name from the Syrian city, but the pepper belt it comes from runs straight across the border into Gaziantep, Kilis, Kahramanmaraş and Şanlıurfa, where the same red peppers have been sun-dried on rooftops for generations.
Since the war in Syria, the trade has moved north. Much of what is sold in Europe and the United States as Aleppo pepper flakes or "Aleppo-style pepper" is now grown and processed in Turkey, sometimes under the name Halaby pepper, sometimes simply as pul biber. So if you buy a good Turkish pul biber, you are buying the pepper most Aleppo pepper recipes were written around.
The differences are small and come down to the producer. Aleppo-style flakes are often a little oilier and saltier, while Turkish pul biber ranges from sweet and fruity to properly hot. In a Turkish shop you will see it sold as tatlı (sweet, very mild) and acı (hot). For a recipe that asks for Aleppo pepper, the everyday Gaziantep flakes are the closest match.
How hot is pul biber?
Less hot than you expect. Aleppo pepper sits at around 10,000 Scoville heat units, and a standard Gaziantep pul biber is in the same neighbourhood: a warm, slow build rather than a sharp sting. Ordinary supermarket chili flakes, the jar Americans call crushed red pepper, are usually made from cayenne-type peppers with all their seeds left in, and are often three to five times hotter.
The heat also behaves differently. Pul biber has more pepper flesh and fewer seeds, so the first thing you taste is fruit and a little salt, then the warmth arrives. That is why Turkish cooks use it by the spoonful, not the pinch. If you are cautious about chili, start with half a teaspoon and taste. If you like heat, look for jars marked acı, or keep a bag of a hotter flake beside the everyday one.
Pul biber, Aleppo, Urfa, Maraş, chili flakes and paprika compared
The jars look similar on a shelf, but they behave very differently in a pan. Here is the quick comparison, in the same order as the bowls in the photo above.
| Pepper | Where from | Looks like | Heat | Tastes like | Best for |
|---|---|---|---|---|---|
| Pul biber | Gaziantep, Kahramanmaraş and Şanlıurfa, Turkey | Coarse, bright red, slightly oily | Mild to medium; hot (acı) versions exist | Fruity, warm, a little salty | Everything: eggs, kebab, butter drizzles, salads |
| Urfa pepper (isot) | Şanlıurfa, Turkey | Dark purple to almost black, moist flakes | Mild with a slow build | Smoky, raisin, dark chocolate | Grilled meat, lentils, beans, dips |
| Maraş pepper | Kahramanmaraş, Turkey | Brick red, coarse | About 10,000 to 15,000 SHU | Rounder and a bit hotter than pul biber | Kebab, soups, stews |
| Sweet paprika | Hungary, Spain, Turkey | Fine powder | Very mild | Sweet, peppery | Colour and gentle warmth |
| Chili flakes | Various, often cayenne-type peppers | Thin flakes, lots of seeds | Usually much hotter | Sharp heat, little fruit | Pizza, when heat is the point |
| Aleppo pepper | Aleppo region; today largely grown in Turkey | Coarse, deep red, oily | About 10,000 SHU | Fruity, lightly tangy | Use it exactly like pul biber |
If you only buy one, buy pul biber. Add isot when you want smoke, and keep paprika for colour.
Aleppo pepper substitute: what can I use instead?
The honest answer is pul biber, one for one. It is the same family of pepper and gives the same colour, fruitiness and gentle heat, so the recipe will taste the way the writer intended.
If you have no Turkish pepper at all, here is how to get close with what is in your cupboard:
- Sweet paprika plus a pinch of chili flakes: four parts paprika to one part chili flakes. You get the colour and the warmth, though not the oily, flaky texture.
- Maraş pepper: one for one, slightly hotter and rounder. If a deli has it, it is an excellent swap.
- Urfa pepper (isot): use it where the pepper is cooked into meat, beans or a dip. It is smokier and darker, so it changes the character of a dish rather than copying Aleppo.
- Ordinary chili flakes: use half the amount, because they are much hotter and carry more seeds.
- Cayenne: a last resort, a quarter of the amount, mixed with paprika for colour.
One swap that does not work: sumac. It sits next to pul biber on every Turkish table, but it is a sour, lemony berry with no heat at all, so it does a different job. For finishing a dish, a sprinkle over hummus, eggs or a salad, nothing replaces the look of real pepper flakes. That is where it is worth having a jar.
How is pul biber used in Turkish cooking?
Everywhere, which is the short answer. Pul biber sits on Turkish tables next to the salt and dried mint, and people add it the way others add black pepper. A few of the places it really earns its keep:
Sizzled in butter. Melt a spoon of butter until it foams, stir in a teaspoon of pul biber, and pour it over poached eggs on garlic yogurt (çılbır), over Turkish dumplings (mantı) or over a bowl of lentil soup. The butter turns brick red and carries the flavour across the whole dish.
With eggs. It goes into menemen, the soft scrambled eggs with tomato and green pepper, and onto fried eggs in the pan at breakfast.
With meat. Kebab houses mix it into minced lamb for Adana kebab and put a bowl of it on every table. A spoon of it in a marinade with yogurt and pepper paste is the base of a lot of home grilling.
In dips and salads. It is the warmth in muhammara, the red pepper and walnut dip, and in ezme, the chopped tomato and pepper salad served with kebab. Onion slices tossed with pul biber, sumac and parsley are the classic kebab side.
At breakfast. A plate of white cheese drizzled with olive oil and a pinch of pul biber is as Turkish as it gets. For a Gaziantep version, swap the pinch for zahter, a breakfast blend that already contains thyme, sumac, sesame and red pepper flakes.
How to choose and store pul biber
Good pul biber is bright brick red, coarse rather than powdery, and looks very slightly glossy because a little oil is often worked in during processing. It should smell sweet and fruity when you open the bag. Brown or dull flakes, a dusty texture or a smell of nothing at all mean old stock.
Keep it in a closed jar, away from the stove and out of the light, which fades the colour first and the flavour soon after. It is at its best within about six months of opening. In a hot kitchen, the fridge is fine and keeps the colour longer. A tip from Turkish grandmothers: if the flakes clump, they still have their oil, which is a good sign.

Pul biber questions, answered
What is pul biber in English?
Turkish red pepper flakes. "Pul" means flake and "biber" means pepper. In English recipes it is usually called Aleppo pepper, Turkish chili flakes or Turkish red pepper.
Is pul biber hot?
Mildly. A standard pul biber is around the heat of Aleppo pepper, roughly 10,000 Scoville units, with a slow, fruity warmth. Hot versions sold as acı are spicier.
Is pul biber the same as chili flakes?
No. Supermarket chili flakes are usually made from hotter cayenne-type peppers with all the seeds left in. Pul biber is milder, fruitier, coarser and a little oily.
What is the best substitute for Aleppo pepper?
Turkish pul biber, one for one. Without it, mix four parts sweet paprika with one part chili flakes.
What is isot pepper?
Urfa pepper from Şanlıurfa. It is sun-dried by day and wrapped at night so it sweats, which turns it almost black and gives it a smoky, raisin-like taste.
Where can I buy pul biber?
We ship Gaziantep pul biber, Urfa isot and Turkish red pepper paste from Turkey, with free shipping on orders over 100 US dollars.
Is pul biber good for you?
We sell spices, not health advice, so we will leave that one to your doctor. What we can tell you is what is in the bag: dried red pepper, sometimes a little salt and oil. It is there for flavour.
If you buy one Turkish spice this year, make it pul biber. Melt a spoon of butter, stir in a teaspoon of flakes and pour it over eggs. You will understand why it is on every table in Turkey.
