Baked Halibut in a Yogurt Sauce

• 1 large onions peeled and thinly sliced
• 3 tablespoons vegetable oil
• 1 teaspoon ginger freshly grated
• 1/2 teaspoon cayenne pepper
• 2 tablespoons coriander seeds ground
• 1/4 teaspoon cumin ground
• 1/4 teaspoon garam masala
• 1/4 teaspoon black pepper freshly ground
• 1 teaspoon salt
• 1 teaspoon sugar
• 1/2 x lemon juice
• 450 millilitres yogurt natural
• 1000 grams halibut fillets 3cm thick
• 50 grams butter, unsalted cold, cut up into small chunks

1. Heat the oven to 190C, gas mark 5
2. Lay the onions on the bottom of a large based baking dish, one that is big enough to lay the fish flat in one layer.
3. Cut the fish into four equal sized portions and place on the onions.
4. Mix the Yoghurt with the lemon juice, salt, pepper, garam masala, cumin, coriander, cayenne, ginger and oil, mixing well.
5. Pour the sauce onto the fish, making sure that some of it goes under as well as over.
6. Cover with either a lid or foil and bake in the oven for approximately 30 minutes, or until the fish is cooked.
7. Pour off the sauce from the fish into a saucepan and boil to reduce to about 350ml of liquid.
8. Whisk in the butter, and as soon as it is melted, pour over the fish and serve.
