Dukkah is an Egyptian mix of coarsely ground spices and nuts, eaten as a dip with olive oil and bread. Typically, it includes cumin, coriander and sesame seeds with variants on the nuts used. We have used one with pistachios. Harissa is available from delicatessens and Middle Eastern food stores. Substitute 1 seeded finely chopped red bird’s-eye chilli and a pinch each of ground cumin and coriander.
