Place the chili peppers in a bowl and cover with hot water. Weigh them down to keep them submerged. Soak for 1 to 2 hours until soft.
Drain the peppers, remove the stems, and most of the seeds (if you prefer less heat). Pat them dry.
The quality and authenticity of Harissa depend on the dried chili peppers. If possible, use Tunisian varieties like 'Baklouti' or 'Beldis', or other medium-hot and smoky peppers. It is crucial to wear gloves when handling the peppers. Harissa is stored in the refrigerator under a layer of olive oil to prevent oxidation and extend its shelf life.

Toast the caraway and coriander seeds in a dry pan for about 1 minute until fragrant. Be careful not to burn them.
Grind the toasted seeds in a mortar and pestle or spice grinder into a fine powder. Add dried mint if using.
In a food processor or blender, combine the soaked peppers, garlic, ground spices, and salt.
Blend until the mixture starts to come together. Gradually pour in the olive oil (about 50-70 ml) while the machine is running until a smooth, thick, spreadable paste forms. Adjust salt to taste.
Transfer the Harissa to a sterilized, airtight jar and press down to remove air bubbles.
Pour a thick layer of extra virgin olive oil (the remaining 30-50 ml) over the paste. The oil serves as a preservative layer.
Store in the refrigerator, where it will last for several weeks. Always ensure the Harissa is covered with oil.
