Chicken with Port and Raisins

1/2 cup dark raisins
1 cup port wine
2 tbsp extra virgin olive oil, divided
4 breasts of chicken
2 shallots, diced
1/4 pound fresh mushrooms
2 tbsp balsamic vinegar
1 cup heavy cream, or evaporated milk
1/4 tsp grated fresh nutmeg
1 tbsp cornstarch mixed with 1 tbsp water
Salt and freshly ground pepper, to taste
Fresh herbs for garnish

Soak the raisins in the port wine at least 1 hour or, preferably, overnight.
Preheat oven to 375 degrees. In a saute pan, heat 1 tbsp of the olive oil. When hot, saute the chicken breasts on one side until golden brown. Turn the chicken over and transfer to an ovenproof dish. Bake for 10 minutes.
In the meantime, in the saute pan, heat the remaining 1 tbsp olive oil. Add the shallots and sweat them for 2 minutes. Add the mushrooms and saute them for 2 minutes. Add the vinegar and reduce until almost dry.
Stir in the raisins and their soaking liquid. Cook until the liquid is reduced by half. Add the cream or evaporated milk, nutmeg, and cornstarch mixture. Cook for 2 more minutes, but do not bring to a boil.
Adjust the seasoning with salt and pepper. Spoon the sauce onto serving plates, set a chicken breast on top, and garnish with fresh herbs.
Couscous would make a perfect side dish.
