Peel the potatoes, cut into pieces, cook in salted water until soft and strain. Mash or press through while still hot and stir with the butter.
Briefly steam the coarsely chopped wild garlic in the vegetable stock and strain, then strain. Heat the milk and stir it together with the wild garlic into the still hot mashed potatoes, refine with cream and season with salt and pepper.
The wild garlic mash is ideal as an accompaniment to briefly roasted meat or fish.
