Harissa

This vibrant homemade harissa is a versatile vegan condiment that brings a punch of smoky heat and aromatic depth to any kitchen. By charring fresh red peppers until soft and toasting whole spices like caraway and cumin, you create a complex flavour profile that far surpasses shop-bought alternatives. The balance of spicy chillies and zesty lemon juice makes it an essential staple for those who enjoy bold, Middle Eastern-inspired flavours.

As a healthy, plant-based addition to your fridge, this savoury paste works beautifully as a marinade for roasted vegetables or stirred into a hearty lentil stew. It is incredibly easy to prepare in batches and stores well in a sterilised jar, ensuring you always have a hit of spice ready to elevate a simple weekday meal or a Sunday roast.

Ingredients for Harissa

  • 1 red pepper

  • 1/2 teaspoons coriander seeds

  • 1/2 teaspoons cumin seeds

  • 1/2 teaspoons caraway seeds

  • 1 1/2 tablespoons olive oil

  • 1 small red onion, coarsely chopped (scant 100g / 90 g in total)

  • 3 cloves garlic, coarsely chopped

  • 3 hot red chillies, seeded and coarsely chopped

  • 1 1/2 teaspoons tomato paste

  • 2 tablespoons freshly squeezed lemon juice

  • 1/2 teaspoons salt

How to make Harissa

Place the pepper under a very hot grill, turning occasionally for about 25 minutes, until blackened on the outside and completely soft. Transfer to a bowl, cover with plastic wrap, and allow to cool. Peel the pepper and discard its skin and seeds.

Place a dry frying pan over low heat and lightly toast the coriander, cumin, and caraway seeds for 2 minutes. Remove them to a mortar and use a pestle to grind to a powder.

Heat the olive oil in a frying pan over medium heat, and fry the onion, garlic, and chillies for 10 to 12 minutes, until a dark smoky colour and almost caramelized.

Now use a blender or a food processor to blitz together all of the paste ingredients until smooth, adding a little more oil if needed.

Store in a sterilized jar in the fridge for up to 2 weeks or even longer.
