Anyway, this recipe is AMAZING, taken from the BBC site - I would VERY strongly advise you to skin the mullet and remove the blood line / lateral line as the flavour is quite strong.
BBC - Food - Recipes : Tandoori grey mullet with cep salad
For the marinade
1½ tbsp ginger and garlic paste
1 tsp black pepper
½ tsp garam masala powder
1 tbsp ground coriander
½ tsp ground cumin
½ tsp chilli powder
2 tbsp vegetable oil
salt, to taste
1 tbsp lemon juice
1 tbsp yoghurt ( I use ground almonds instead )
Fresh, chopped Corriander - lots
Fillet your mullet and skin it. Slice into goujons and add to the marinade
Preparation method
Mix all of marinade ingredients together in a bowl until well combined.
Place the grey mullet into a dish, pour over the marinade and rub it into the fish. Set aside to marinate for 30 minutes.
Preheat the grill to high. Grill the fish for 2-3 minutes on each side. Baste with the lemon juice, butter and chat masala.
I bet it would be great skewered and done on the BBQ. I'd serve this with rice, mango chutney and maybe some asparagus
Seriously, if this doesn't convert you to the joys of mullet, nothing will!
