The Kenyan coast is a wonderful mix; native tribes influenced by Arabic trade and Indian settlement. The food is coconut and seafood-rich, and I’d always seek out a Swahili curry on my first day at the coast. Coastal people eat a lot more spice than those in Nairobi with green chilies (pilipili) featuring in most dishes.
To reheat: Gently heat in a pan with the lid on so it doesn’t dry out or overcook the fish, or use the reheat setting on your microwave.
