There’s a jar in almost every Turkish kitchen that quietly does more work than anything else on the shelf. It holds a dark, glossy red paste, thick enough to stand a spoon in, tasting of sun-dried peppers, salt and slow patience. Ask for it in a market in Gaziantep or Kahramanmaraş and you’ll hear it called biberk: pepper paste, the concentrated heart of a cuisine that treats chillies as a foundation rather than a garnish.
Biberk isn’t a single product, though. It’s a whole family of pastes made from peppers that have been cooked down, salted and often dried outdoors before being ground into something between a purée and a spice. Once you understand what’s in the jar, using it becomes second nature.
What biberk actually is
At its simplest, biberk is peppers, salt and time. Red peppers are cooked or sun-dried until most of the water disappears, salted heavily, then ground into a dense paste. A useful rule of thumb from home producers: 4kg of fresh peppers ends up as roughly 1kg of finished paste. Everything that vanishes is water.
That concentration explains how it behaves in a pan. It doesn’t splash and steam the way fresh peppers do. It darkens, thickens and coats whatever it touches, which is why one spoonful can carry an entire pot of beans or a tray of roasted vegetables.
Sweet, hot, or somewhere in between
Turkish shops label the two ends of the range clearly. Tatlı means sweet, and despite the name it isn’t sugary. It’s the mild version made from red bell-type peppers, with a rounded, almost tomato-like depth. Acı means hot, and the heat swings wildly between producers. A gentle acı biberk barely registers; a fierce one from Kahramanmaraş will make you rethink how much you spooned into the pot.
The main varieties you’ll come across
- Antep biberk: Made from thick-fleshed peppers grown around Gaziantep. Sweet, deep red, faintly fruity. The sensible default for most cooking.
- Isot (Urfa biber): Urfa-style peppers dried and ground with a little oil. The colour is a dark maroon and the flavour leans smoky and raisin-like, with heat that arrives late and fades slowly.
- Maraş biberk: Sharper and hotter than Antep, with a cleaner, more vegetal bite. Good in soups where you want the heat to spread evenly rather than sit in one corner.
- Mixed pastes: Some producers blend in tomato, garlic or walnuts. Delicious, but check the label if the pepper should be the only flavour in the dish.
- Export blends: Sold abroad as Turkish red pepper paste. Quality varies enormously, so buy small jars until you find a producer you trust.
How the paste is made, traditionally
Late summer is pepper season. Families buy peppers by the crate, split them, remove stems and most seeds, and lay them out on cloths across flat rooftops. For three to seven days they sit in the sun, turned once or twice a day, until they’re wrinkled and leathery. Then they’re salted at roughly a tenth of their weight and left overnight so the last of the liquid drains away.
Grinding comes next. A stone mill gives the smoothest result, but a heavy-duty blender handles it at home. Some cooks stop there and jar the paste raw. Others cook it down in a wide pan with olive oil for an hour or more, which darkens the colour and pushes the flavour toward caramel and smoke.
Why the salt level is so high
Biberk historically had to survive a winter without refrigeration, so salt was the preservation method. That’s why old-fashioned pastes taste almost aggressively savoury. Commercial jars today are usually milder, and a paste that seems too salty to use straight is a sign of a traditional recipe rather than a mistake.
Cooking with biberk: where it earns its place
Breakfast
Stir a teaspoon through scrambled eggs, or spread a thin layer on flatbread before adding cheese and grilling it. In menemen, the Turkish scrambled-egg-and-tomato dish, a spoonful of acı biberk alongside the tomatoes adds a background heat that fresh chillies simply can’t match.
Soups, stews and beans
Kuru fasulye, the white bean stew on every Turkish menu, is essentially beans, onion, tomato and biberk. Use about one tablespoon for four servings, fry it in the oil with the onion for 30 seconds before adding liquid, and the whole pot changes colour and character. The same trick rescues lentil soup, braised greens and any tomato sauce that tastes flat.
Marinades, dips and quick sauces
Mix equal parts biberk and thick yoghurt with a crushed garlic clove for an instant dip. Thin it with olive oil and lemon for a dressing that works on grilled fish. For chicken or lamb, combine two tablespoons with yoghurt, paprika and salt, then marinate for at least four hours; the paste clings far better than a dry rub ever will.
What to look for when you buy
Colour is the first clue. A good paste is deep brick or maroon red. If it glows neon orange, dye is doing the work. Turn the jar over and read the ingredients: peppers, salt, sometimes a little olive or sunflower oil. That’s it. An unpronounceable list usually means stabilisers.
Check the surface for a thin layer of separated oil. That’s normal. A sour, fizzy smell is not. In person, buy from a shop with high turnover, because paste that has sat on a warm shelf for a year loses its brightness fast.
Storing it so it lasts
Once opened, biberk belongs in the fridge. Smooth the surface flat, pour a thin film of olive oil over the top and seal the jar. The oil keeps air away and stops mould forming. Handled that way, a jar stays good for six to twelve months.
For longer storage, spoon the paste into an ice cube tray, freeze it, then transfer the cubes to a bag. Each cube is roughly a tablespoon, which makes it easy to drop one straight into a hot pan.
Four mistakes that ruin a good jar
- Treating it like tomato paste. Biberk is saltier and more intense. Start with half the amount you’d use of tomato paste and adjust from there.
- Skipping the frying step. Raw paste tastes sharp. Thirty seconds in hot oil mellows it and releases the aroma.
- Leaving it in the cupboard. Unopened it’s fine. Opened, it darkens and eventually spoils at room temperature.
- Buying the biggest jar. A 700g jar is only a bargain if you’ll finish it. Start at 300g.
Making your own, if you have a sunny week
Buy 3kg of red peppers at the end of summer, split and deseed them, and lay them on clean cloths in direct sun for three to five days, bringing them indoors at night. Salt them with about 300g of coarse salt, leave overnight, drain, then blend. Cook the purée in a wide pan over low heat for 45 minutes with a splash of olive oil, stirring often, until it holds its shape on a spoon. Jar it hot, top with oil, and you have something no supermarket version quite matches.
