Preheat the oven to 400 degrees F. Season the chicken with olive
oil, salt and pepper.
Place on a roasting pan and bake for 30 minutes. Reduce the heat
to 350 degrees F. and
continue to cook for 30 minutes. In a large saute pan, melt
the butter. Add the ham and
saute for 2 minutes. Add the onions. Saute for 1 minute. Add
the garlic and mushrooms.
Season with salt and pepper. Saute for 2 minutes. Add the peas
and potatoes. Saute for 3
to 4 minutes. 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.
Add the egg yolks and whisk, over low heat, until frothy, about
3 to 4 minutes. In a steady
stream, add the butter until the sauce thickens. Season with
salt and pepper. Strain the
sauce through a chinois and set aside. Remove the chicken from the
oven and carve into 4
pieces (2 breast and 2 leg/thigh). To serve, spoon the potato
mixture on the bottom of
each plate. Lay the individual chicken portions on top of the
potatoes. Spoon the Bernaise
Sauce over the chicken and serve.
