Light, lemony flavors make this sauce the perfect partner for chicken and fresh garden vegetables. Our recipe begins with Chardonnay, shallots and chicken demi-glace. We balance it with earthy mushrooms, lemon and a splash of Champagne vinegar. Ingredients are simmered for hours for rich, homemade flavor. Just combine the starter with chicken in a slow cooker or Dutch oven, then add fresh spring asparagus and peas during the last few minutes of cooking. Serve over steamed rice or buttered noodles.
