In the classic lamprey pie preparation, what two key components are used to flavor and potentially balance the strong characteristics of the fish?

Answer

Pastry crust and a rich sauce made with wine or vinegar

The traditional European preparation, lamprey pie, relies fundamentally on baking the lampreys encased within a pastry crust. Crucially accompanying this is a rich sauce, which traditionally incorporates wine or vinegar. This acidic component serves a vital purpose beyond mere flavor enhancement; it is employed to temper or cut through the naturally strong characteristics inherent to the lamprey, suggesting historical cooks recognized the need to balance the flavor profile significantly.
