Iced Biscuit Napolitaine

Biscuit glacé Napolitaine (Neapolitan iced biscuit) teaches one true thing: a striped frozen dessert is made by boundaries, not by colours. Vanilla must remain ivory, strawberry clear and rosy, Pralin warmly tawny. That only happens when each band is packed level and frozen firm before the next one touches it.

The original entry assumes a pâtissier who can reach for vanilla and pralined biscuit preparations, strawberry ice already churned, and a metal mould ready for salted ice. Your home equivalent is a single pâte à bombe (cooked-yolk foam) divided between vanilla and Pralin, a small batch of strawberry ice, a loaf tin, and an ordinary freezer. Combining the two biscuit preparations removes brigade scaffolding because their structure is the same; the separate flavours and three-stage freezing remain because they are the dish. One cook, one stove, one evening.

When it is cut, the slice should stand straight but yield immediately to the spoon, creamy at the outer bands and brightly fruity through the middle. Don't rush the assembly. Pack every band level, then freeze it until a fingertip cannot dent it before the next goes on.
