Karen Martini's masala marinated mackerel.William MeppemThis masala paste is quite punchy and fragrant,making it ideal for a rich and oily fish. The crunchy onion salad is also a great foil for the spiced fish,especially if perfumed with smoke from grilling over real coals. A griddle pan or gas barbecue will do a fine job,too,just get the surface as hot as possible before cooking. You could substitute sardines,sand mullet or salmon cutlets for this,but remember to adjust the cooking time accordingly.
