Heat the oven to 220C/200C fan/gas 8. Roast the peppers for 25-30 mins, turning halfway, until tender and starting to blister (if they don’t blister, grill them for a few minutes). Cool a bit, then peel and discard the skins. Discard the seeds and finely chop the flesh. Toast the walnuts for 5 mins until lightly browned.

Grind all but four of the walnut halves in a spice grinder until they are quite fine but still have some texture. Mix the ground walnuts with the peppers, then add the molasses, spices, tomato paste, garlic, breadcrumbs and sea salt, mix well and season.

Serve the muhammara on a small plate, drizzling with some olive oil. Add the whole walnuts to the centre and some coriander around the edge.
