Frivolities

Frivolités (small filled pastry boats) teach proportion. The one true thing to know before touching a pan is this: shell and filling must each be cool, dry, and properly seasoned before they meet. A damp filling ruins crisp pastry, while too much filling turns an elegant first bite into a small pie with ambitions.

The classical entry defines a family, not a fixed garnish. Its kitchen assumed a pâtissier turning out ranks of tiny shells and a garde-manger holding many fillings ready for service. At home, 24 baked Barquettes (No. 314) and three contrasting garnishes preserve the intent without pretending you have a brigade in the pantry. The parade of dozens is scaffolding and can go; the crisp shell, concentrated filling, and variety are the dish and must stay. One cook, one stove, one evening.

Cook the mushroom duxelles until no loose moisture remains, keep the ham mousse cold enough to hold its shape, and dry the shrimp before binding it. If a filling loosens, don't surrender the shells to it. Reduce or chill the filling first, ça se rattrape. The step that decides everything is the last one: fill the Barquettes (No. 314) only shortly before they go to the table.
