1 Set the oven to 200 degrees.

2 Mix the sesame oil, soy sauce and water in a bowl, then peel and grate the garlic and ginger into it; whisk together.

3 Spoon two tablespoons of the mixture on the base of a small roasting tray or casserole dish, lay the hake on top, moving it around the base to make sure it doesn't stick while cooking.

4 Slice the mushrooms, halve the mangetout, shred the carrot and cut up the spring onions and mix them all together and lay on top of the hake.

5 Spoon the remaining soy dressing over the top.

6 Cover tightly with foil and bake for 15-20 minutes, depending on the thickness of the fish.

7 It will be be necessary to have a peek at the 15-minute stage; it's best to use a small knife to check if the fish is cooked. If in doubt, just cover it tightly again and pop it back in the oven for a few more minutes.

8 Serve with some fresh coriander and jasmine rice.
