Place the potatoes in the oven and roast the potatoes until golden brown and tender, about 20 minutes, shaking the pan every 5 minutes. Remove from the oven and add the parsley. For the Sauce: In a saucepan, combine the vinegar, wine, peppercorns, shallots, and tarragon. Bring the liquid to a boil and reduce to 1 tablespoon. Add 1 tablespoon of water. Combine the reduced liquid and egg yolks in a stainless bowl, over simmering water. Whisk until frothy. In a steady stream, add the butter until the sauce thickens. Season with salt and pepper.
