Baked cod with Greek lemon potatoes

Method

1. Preheat the oven to 200°C/gas 6.

2. Spread the potatoes in a roasting pan or gratin dish into which they will fit snugly.
Scatter over the onion, garlic and oregano. Season to taste with salt and pepper.

3. Pour in the olive oil and lemon juice. Add enough water to barely cover.

4. Bake for 45 minutes. Turn the mixture over and bake for a further 45 minutes, or until the potatoes are cooked through.

5. When the potatoes are nearly ready, place the cod skin side down in a thickly buttered gratin dish. Dribble a thin layer of best olive oil over the surface, and season well.

6. Bake for 15 minutes, then test with a knife point or skewer. If it goes right through with no resistance, the fish is cooked.

7. Serve the potatoes alongside the fish with plenty of the oily, lemony juices.
