Lyonnais Poulet Célestine with tomato, mushrooms, Cognac and white wine
Poulet Célestine is a Lyonnais preparation built around chicken, tomato, mushrooms, Cognac and dry white wine. Accounts link the name with chef Jérôme Rousselot and Célestine Blanchard, but the romantic story is best treated as an associated tradition rather than a fact that the cook needs to accept as proven. The culinary identity is clearer: sautéed chicken, a wine-and-Cognac sauce, mushrooms, tomato, garlic and parsley.
Butter is used for browning, but there is no cream in this household interpretation. That keeps it materially different from the Bresse, Loué, Gaston Gérard and Vallée d’Auge dishes in the same collection. The vegetables are cooked just enough to become saucy, then the wine, stock and Cognac are simmered before the chicken returns for a covered braise.
The sauce is reduced only after the chicken has reached 74 °C and has been removed from the pan. This sequencing matters: it concentrates the liquid without forcing already-cooked meat through an unnecessary hard boil. Garlic and parsley are stirred in off the heat so they read as a fresh finishing note against the mushroom and tomato base.
