Clean and wash the fish, drizzle lemon juice over it and leave it for half an hour. Then season with salt and pepper.
Put the prepared fish into a baking pan or ovenproof dish, on small amount of olive oil together with potatoes, peeled and cut into bigger pieces. Bake in a preheated oven at 220°C.
Combine olive oil, wine, water, halved garlic, pepper, bay leaf, rosemary and Vegeta Gourmet Stock Powder in a pot and simmer for few minutes.
When the fish and potatoes are half baked, pour over prepared oil, wine and herb mixture and bake until done. Baking time is approximately 40 minutes.
If Groper fish is not availabe you can replace it with Snapper fish of the same size.
If you have a larger fish you can speed up cooking time by making a cut through the thickest part of the fish and place the cut side up while cooking.
The secret of this dish is in a combination of baking and cooking of the fish.
