Put fish, shrimps, red chillies, red curry paste, salt, brown sugar, Kaffir lime leaves in a mixer jar and grind. Add desiccated coconut and grind till smooth. Heat extra virgin olive oil in a grill pan. Dampen your palms, take a portion of the fish mixture and pat it onto a satay stick and flatten. Similarly prepare more satays.
Place them on the grill pan and cook, turning sides so that they get cooked evenly all around, till golden. Serve hot.
