Fajita seasoning mix

Use a fajita mix for these fish tacos to give you all the right flavours without having to buy jars of individual spices. To make fajita seasoning mix sauce, put all of its ingredients in a food processor, blitz until smooth and season well.

Add a splash of water if you need to, to make it a consistency that can be drizzled, then pour into a bowl or jug and chill until needed. To make the fish, whisk the lime juice, oil and fajita seasoning in a bowl, add the cod and toss well. Fry the cod in a non-stick frying pan over a high heat for 5 mins until beginning to flake, but not falling apart. Which fish is best to use in fish tacos?
