To make the marinade add the lemon juice, garlic, saffron, olive oil, coriander leaves, salt, chilli flakes, red onion, paprika and ground coriander to a blender. Blend into a smooth paste. You can add a few drops of water just to loosen the ingredients when blending, only if required.
Cut the fish into cubes., about 3 x 3 cm. Add the marinade to the fish and mix it into the fish> Refrigerate for half an hour
Soak skewers in some water for about 30 minutes, this will help prevent it from burning on the grill
Thread the fish into the skewers. If you are using peppers, onion and tomatoes you can add them in between the fish
Grill on a hot braai or in a griddle pan, on the stovetop on medium-high heat. I grease a piece of foil with some oil, place it on the braai grill and then I cook my skewers on the foil. You can place it straight on the grill if you are comfortable with that. Serve hot with a drizzle of lemon juice and a fresh salad
