Peel the potatoes, cut them into pieces, and put them in a saucepan with water, then cover.
3. Cook for 15 to 20 minutes or until the potatoes are tender, then strain them.

Peel and finely chop the shallot, put it in a saucepan with red wine and veal stock, heat over medium heat and reduce.
9. Reduce the heat to low and gradually add the butter in small pieces, whisking the sauce, then keep warm.
