Dacquoise — Nut Meringue Disc

Dacquoise is a nut-enriched meringue disc that provides both structure and flavour in layered entremets and gâteaux. Originating from Dax in southwest France, it combines a French meringue base with ground nuts — traditionally almonds, hazelnuts, or a blend — and a small proportion of starch or flour that stabilizes the disc during baking. The standard ratio is 150 g egg whites : 100 g caster sugar for the meringue, folded with 150 g ground nuts and 30 g icing sugar sifted together, plus 15-20 g cornflour. The egg whites are whipped to medium peaks — not stiff, as overwhipped whites shatter when the heavy nut meal is folded in — then sugar is streamed in gradually. The nut mixture is folded by hand in two additions, using broad strokes that cut through the centre and rotate the bowl, aiming for a homogeneous batter that still holds visible volume. The batter is piped onto parchment in concentric spirals using a 10-12 mm plain tip, building discs 2 cm thick and dusted with icing sugar before baking. This sugar coating caramelizes at the surface, creating a thin crust while the interior remains chewy. Baking at 150-160°C for 35-45 minutes dries the meringue slowly; the discs should be uniformly golden, firm to the touch, and yield slightly when pressed in the centre. Residual moisture in the interior — roughly 8-12% — is essential. Over-drying produces a brittle disc that crumbles during assembly. Once cooled, dacquoise discs can be stored in airtight containers for 48 hours at room temperature or frozen for up to three weeks. In assembly, they are typically paired with praline buttercream, ganache, or fruit-based creams.
