Clean and wash the Brussels sprouts and cut the stalk crosswise. Peel and halve the shallots. Clean the mushrooms and, depending on their size, leave them whole or cut into slices. Heat the fat in a pot, fry the shallots and mushrooms lightly and season with salt, pepper and thyme.
Deglaze with veal stock, bring to the boil and add Brussels sprouts. Cover and cook for 15-20 minutes. Season to taste with salt and pepper. Cut Roquefort into cubes. Arrange soup in deep plates and sprinkle with Roquefort cubes.
Sprinkle with crushed pink berries and serve garnished with fresh thyme. Baguette tastes good with it.
