Biber salçası vs Harissa
The short answer
Two red pepper pastes cooked into food. Harissa is dried chillies pounded with garlic, caraway and coriander, and it is hot and spiced. Biber salçası, as its two Turkish registrations describe it, is ripe red pepper and salt and nothing else, reduced in the sun or by boiling; it may be sweet or hot, and it tastes of the pepper.

| Biber salçası | Harissa | |
|---|---|---|
| Defining ingredients | Ripe red pepper, fresh, salt | Dried red chillies, rehydrated, Garlic, caraway, coriander seed, cumin, Salt |
| Origin | Southern and south-eastern Türkiye. The two registered pastes are those of Gaziantep and Hatay provinces, and a study from Osmaniye says making pepper into paste is especially common in the south of the country. None of the sources read says when it began; the registrations say only that it has a long past. | Tunisia, where it is a daily condiment rather than an occasional seasoning, with related preparations across Algeria, Libya and Morocco. Its existence depends on chilli, which reached North Africa after Columbian contact, so harissa is a comparatively recent tradition built on an old one. |
| Cuisines | Turkish | North African, Moroccan, Middle Eastern |
| Heat | Sweet or hot, as made. The kapya pepper of the Hatay paste is a sweet one; hot pepper is added for a hot paste. | Moderate to hot, varying widely by the chilli used. Tunisian versions are generally hotter than the rose harissa commonly sold in Britain. |
| Flavour | Concentrated ripe red pepper, salted. The Hatay registration describes its own paste as having a strong pepper smell from the sun-drying, a thick body and a dark colour, and says it no longer tastes like the fresh fruit. No tasting panel has described the paste itself. | Hot, but the heat is not the point — a good harissa is fruity from the rehydrated chillies, sharp with garlic, and carries a distinct anise-adjacent note from the caraway that nothing else in North African cooking supplies. Commercial versions that skimp on caraway taste like generic chilli paste, which is the difference most people notice without being able to name. |

Which should you buy?
Biber salçası
Two things vary: how the water is taken out, and whether the paste is hot. In Hatay the cut peppers are dried in the sun for two to three days before they are minced, and the registration credits that drying with the paste’s dark colour and strong smell. In Gaziantep the peppers are crushed to a pulp and reduced under vacuum in a factory, and nothing is dried in the sun. The Hatay paste is thicker and saltier on its own figures. Hot pepper may be worked into the sweet. In Şanlıurfa, where the paste is made from the local isot pepper, a study describes a third way: at home the peppers are washed, cut up and minced first, and the mince is then left in the sun until it is thick enough, where the Hatay method dries the strips before mincing. The study says the paste ferments as it stands and credits that with a better smell and look; it reports this from an earlier work and did not measure it. A survey of households in one district of Osmaniye found that most made their own to suit their own taste, and it records no recipe.
Harissa
Harissa varies by household, by region and — most consequentially for anyone buying it — by whether it is a paste or a powder. The traditional product is a wet paste of rehydrated chillies pounded with garlic, spices, salt and olive oil, and it is used by the spoonful. A dry powder sold under the same name is a different ingredient with different behaviour: it has no oil to carry the aroma, no garlic, and it needs rehydrating or blooming to be usable. Rose harissa, now widely sold in Britain, adds dried rose petals and is a genuine regional variation rather than a marketing invention, though it is sweeter and milder than most Tunisian versions. Caraway is the component most often reduced or omitted in commercial paste, and its absence is the commonest reason a jar tastes like generic chilli paste.
