Harissa is a North African chilli paste — fiery, aromatic and considerably more interesting than a generic hot sauce. It's built around rehydrated dried red chillies with toasted caraway, coriander and cumin seeds, garlic and olive oil. The result is a deeply flavoured paste that works as a marinade, a condiment, a soup stirrer, and an instant way to liven up almost anything on the hob.

Homemade harissa paste recipe — dried chillies, caraway and coriander seeds – The Flexible Chef
This homemade harissa paste recipe is simple to make and keeps well in the fridge. The only patience required is in the toasting — don't rush it, and don't burn the seeds.
The Harissa Paste Recipe
Ingredients
- 75g dried red chillies, rehydrated in boiling water until soft — drain but reserve the soaking liquid
- ½ tsp coriander seeds, toasted
- ½ tsp caraway seeds, toasted
- ½ tsp cumin seeds, toasted
- 2 garlic cloves, peeled and smashed
- A pinch of sea salt
- Extra virgin olive oil
- Fresh lemon juice
- Optional: a few sun-dried tomatoes packed in oil
Method
- Dry-fry the coriander, caraway and cumin seeds in a pan over a medium heat until fragrant. Don't burn them. Leave to cool completely, then grind to a powder in a pestle and mortar or spice grinder.
- Stem the rehydrated chillies and remove most or all of the seeds depending on how much heat you want.
- Add the chillies, garlic, ground seeds, salt and a squeeze of lemon juice to a blender. Drizzle in olive oil slowly while blending until a paste forms. If it needs loosening, add a little of the reserved soaking liquid.
- If you have sun-dried tomatoes packed in oil, add a few now — they add a rich, jammy depth to the finished paste.
- Decant into a sterilised jar and top with a slick of olive oil. Keeps for several weeks in the fridge.
What to do with it
Harissa works well beyond North African cooking. Use it as a marinade base for chicken or lamb, stir a spoonful into a soup or stew, or add it to a curry sauce when you want heat with complexity rather than just heat. The Spiced Beef Mince with Couscous on this site is a natural pairing — a spoonful of harissa stirred through the mince before serving adds exactly the right kind of fire.
For a simple side, try harissa carrots — an idea I first picked up from Nigel Slater years ago. Blanch young carrots whole until tender, then while they're still warm, dress them with a mix of mashed garlic, an egg yolk, olive oil, a splash of white wine vinegar, a teaspoon of Dijon, and a good spoonful of this harissa. A proper side dish alongside almost anything off the grill.
