Onions peel and quarter. Wash the goose legs. Boil up about 3/4 litre salted water. Add goose legs, onions, bay leaf, peppercorns, juniper berries and pimento and simmer covered for about 45 minutes.
Meanwhile, peel the turnip, potatoes and carrots and cut into large cubes. Clean and wash the leek and cut into thick rings. Wash the thyme. Put something aside for garnishing. Pluck the leaves from the stems.
Take out goose legs and let them drip off on kitchen paper. Degrease broth and bring to the boil. Cook the vegetables and thyme for about 25 minutes. Season goose legs with salt and pepper and put them on the fat pan of the oven.
Roast in the preheated oven (electric cooker: 200 °C/ gas: level 3) for about 30 minutes. Season vegetables with salt and pepper. Serve with the goose legs. Garnish with laurel and thyme.
