Harissa Powder: Tunisia’s Chile Seasoning, Dried and Ground

A chile paste on UNESCO’s heritage list? Tunisian harissa, and the practices around making it, went on in 2022.¹ Harissa powder is the dry form: ground dried chile with garlic and spices like coriander, caraway and cumin, ready to stir into oil or sprinkle straight on food. There’s no single recipe. The traditional paste is chile, salt, garlic and coriander pounded together, while American blends tend to add cumin and smoked paprika, and one even lists tomato powder first.

What harissa is

UNESCO calls harissa a seasoning made with chilli pepper paste and an integral part of household provisions in Tunisia.¹ It’s a spicy North African paste made from dried chilies, salt, oil and other seasonings. Gernot Katzer calls Tunisian harissa a fiery paste of dried chiles and notes that several recipes for it call for caraway, as does zhoug, a similar preparation from Yemen.²

How the paste is made. In UNESCO’s account, the chilies are dried in the sun, then stemmed, seeded and rinsed, and crushed with salt, garlic and coriander using a pestle and mortar or a hand-cranked meat mincer. The paste is stored in glass or pottery. Making it is usually a job for the women of a household, done together in a festive family setting.¹

The name. Merriam-Webster traces harissa through French to North African Arabic harīsa, a derivative of Arabic harasa, “crush, bruise, pound.” All that pounding fits the mortar described above, though none of the sources we opened say that’s where the name came from. Merriam-Webster dates the first known English use, in this sense, to 1970.⁴

Origin of chile in North Africa. Chile peppers are American plants: Capsicum annuum is native from the southern United States to Brazil and the Caribbean. How and when they reached North Africa and found their way into Tunisian cooking, none of the sources we checked say.

What goes into harissa powder

We didn’t find any regulator or standard defining harissa powder. Here’s what five named sources use, side by side:

What stands out:

• Chile, salt, garlic and coriander are the common core, and they’re all that UNESCO’s description of the paste names.
• Caraway shows up in Katzer’s Tunisian recipes, the Oregon State recipe, the Spice House blend and PepperScale’s recipe.
• Cumin is in all three American versions, and smoked paprika in Oregon State’s and PepperScale’s; neither is in UNESCO’s description.
• Mint, sometimes said to be a standard addition, isn’t in any of the five.

Flavor

The Spice House lists garlic, cumin and warm heat as its blend’s taste notes.⁵ In general, harissa powder tastes of dried red chile first, then garlic, the citrusy warmth of coriander and the anise-like note of caraway. It can run from mild to very hot depending on the chile. The Oregon State recipe tells you to use cayenne or any ground red pepper with the heat level you like,³ and PepperScale suggests taking out the chile seeds for a milder version.⁶

How it is used

As a paste. Oregon State Extension suggests mixing the powder with vegetable oil to make a paste for roasting poultry, meat or tofu.³ That gives you a quick stand-in for the traditional paste; see harissa paste vs. powder.

As a seasoning. Oregon State suggests roasted vegetables, sauces, soups and stews. The Spice House suggests grilled vegetables, stews and lentils, eggs, shakshuka and merguez sausage, where it uses 3 tablespoons per pound of ground meat.⁵ PepperScale suggests it as a dry rub for steaks, chicken or a meaty fish, and as extra spice for soups, spreads and dips.⁶

Other uses. Cooks also reach for harissa powder in:

• Couscous, chickpea dishes and lentil soups.
• Marinades for lamb, chicken and fish.
• Yogurt or mayonnaise sauces.
• Roasted carrots and squash.

Technique. For a fresher blend, Oregon State says to toast whole cumin and coriander seeds until fragrant, let them cool, then grind.³

Buying and quality

• Read the label. Commercial blends vary a lot. The Spice House blend lists tomato powder first;⁵ others are mostly chile. Salt is common.
• Smoked or not. A blend made with smoked paprika, as in Oregon State’s recipe, tastes noticeably smoky.
• Color and smell. Bright brick-red powder with a clear garlic-and-coriander smell is fresh. Dull brown powder has faded.

Storage

Oregon State’s recipe says to keep the mix in an airtight container.³ We didn’t find a shelf-life figure for harissa powder from any regulator or standards body. Homemade harissa paste is a different story: keep it in the fridge under a layer of oil.

Nutrition and health

We didn’t find a nutrient analysis of harissa powder. You use it in small amounts, so it doesn’t supply much of any vitamin or mineral. You may see claims that harissa helps prevent obesity or macular degeneration through its calcium or vitamin A content. None of the sources we reviewed back that up, and we’re not claiming harissa treats or prevents any disease.

Safety

• Mycotoxins (EU). EU law sets maximum levels of ochratoxin A (20 µg/kg) and aflatoxins for dried Capsicum spices such as chilli powder, cayenne and paprika,⁷ the base of harissa powder.
• Salt. Commercial blends often contain salt, so taste before you salt the dish.
