This is a meal to impress anyone & simplest to make. Find a good fishmonger & buy some fresh tuna (ask if it’s sashimi fresh!)
Serves 4 – 6
1 onion very finely sliced, use a mandolin if you have one
1 carrot also very finely sliced
handful of water cress or garden cress
500g fresh tuna in one piece – ask your fishmonger to cut an oblong which you can slice
1 chopped garlic clove
1 tbsp chopped fresh ginger
4 tbsp soy sauce
4 tbsp sake or rice wine
4 tbsp lemon juice
2 tablespoons sunflower oil
Put sliced onion and carrot in the middle of on a largish plate.
Mix ingredients for the dressing in a small bowl or jug.
Prepare a large bowl of ice cold water (put some ice cubes in it)
Pour oil in a non-stick frying pan until smoking hot – sear tuna on all sides for approximately 1 1/2 – 2 minutes each side. You can see it cooking (pale brown with slight charring) around the edges, leaving the pink flesh in the middle. As soon as tuna is seared all around, plunge into the ice cold water to stop cooking.
Slice tuna with a sharp knife into 1/2 cm slices. Arrange around the mound of onion/carrot, dress all over with dressing, garnish with watercress.
Approximate cost £15.00 is pretty much only the cost of the tuna.
