Ingredients:
- 3 cups milk
- ½ onion
- 1 bay leaf
- 2 cloves of garlic
- 2 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 1 pinch ground nutmeg
- 12 fresh oysters
- 1 cup grated Parmesan cheese
- Mozzarella cheese for gratin
- Parsley
- Salt to taste
Procedure:
Prepare the béchamel sauce: boil the milk with onion, bay leaf and cloves. Melt the butter, add all-purpose flour and stir until it smells like cookie. Add the boiled milk gradually, stirring constantly to avoid lumps. Season with salt and ground pepper; set aside. Open the oysters ( you can try to open it with your hands, if it is difficult it can boil for a few minutes) and season with a pinch of salt (do not use much salt). Cover with béchamel sauce, sprinkle Parmesan cheese and mozzarella cheese. Take it to the oven for 6-7 minutes, until cheese is melted and golden. Serve immediately with lime.
