This is a cut & paste job but very tasty
Bengali steamed fish with mustard masala
Ingredients
4 tsp black mustard seeds
6 tbsp mustard oil
75g/2½oz onions, peeled, halved and thinly sliced
40g/1½oz garlic, peeled, thinly sliced
1 tsp turmeric powder
2 tsp Kashmiri chilli powder
1 tsp salt
4 x 175g/16oz steaks hake, cod, barramundi or blue-eye trevalla
50g/2oz red onion, peeled, thinly sliced
1 green cayenne chilli, thinly sliced
Method
1. Place the mustard seeds into a spice grinder and grind to a fine powder.
2. Heat the mustard oil in a small frying pan, then add the onions, garlic, turmeric powder, chilli powder, mustard seed powder and salt. Gently fry for 3-4 minutes, or until the onions and garlic are softened and slightly browned.
3. Transfer the mixture into a food processor and blend to a smooth paste. Spread half of the paste over one side of each fish steak.
4. Tear off four 12in/30cm squares of aluminium foil and place each fish steak, paste side down, into the centre of each piece. Spread the remaining spice paste over each fish steak.
5. Scatter the sliced red onion over the fish and sprinkle over the green chilli. Fold up the foil and crimp the edges to seal and make four parcels. Place the parcels into a steamer, cover and steam for 20 minutes, or until the fish is cooked through (the fish should be opaque and flake easily when gently pushed at the thickest part).
6. Unwrap each parcel and lift the fish onto warmed serving plates. Spoon over the juices from the parcels and serve
