Ingredients:

— 2 cloves of garlic

— 3 tablespoons of vegetable oil

— Salt to taste

— Black pepper to taste

— 4 potatoes

— 1 trout

— 1 tablespoon of butter

— 1 egg yolk

— 1 tablespoon of lemon juice

— 1 tablespoon of grain mustard

Preparation:

1. Pass the garlic through a press and mix it with 2 tablespoons of vegetable oil, salt, and pepper. Peel the potatoes and cut them into medium-sized pieces.

2. Rinse the fish, clean it, gut it, and remove the gills. Coat the trout with the garlic sauce and leave it in the refrigerator for 20-25 minutes.

3. Melt the butter, let it cool slightly, then mix it with the egg yolk, lemon juice, mustard, and salt.

4. Grease a baking dish with the remaining vegetable oil. Place the fish and potatoes in the dish and pour over the butter-mustard sauce. Bake for about 30 minutes at 200°C. If the fish or potatoes begin to burn, cover the dish with foil.
