Chicken Liver Mousse

Unlike most pâtés and terrines in which raw ingredients are cooked together in a mold, chicken liver mousse is made with cooked livers, shallots, and thyme pureed with butter, worked through a sieve, and then folded together with whipped cream. The delicate consistency and flavor puts chopped liver to shame, though any taboos about combining meat and dairy are obviously broken. Serve the mousse with little toasts.
