The dacquoise takes its name from Dax, a town in the Landes region of southwest France. It is a nut meringue — ground hazelnuts or almonds folded into French meringue and baked low and slow — used as a structural and flavour base layer in entremets and gâteaux. It is often called a "biscuit dacquoise" in French pastry catalogues but is more precisely a meringue than a biscuit — it contains no flour, no yeast, no fat beyond the natural oil of the nuts, and its structure comes entirely from egg white foam.
The dacquoise's purpose within an entremet is twofold: structural (it provides a dry, firm base that supports the cream layers above it without softening as rapidly as a soaked sponge would) and flavour (the combination of toasted nuts and caramelised meringue at the edges provides a roasted, caramel-hazelnut note that anchors the composition). The technique: make a French meringue (egg whites beaten with caster sugar to stiff peaks), then fold in icing sugar and finely ground toasted nuts (the ratio is approximately 1:1 nut to meringue by weight). Pipe onto lined baking sheets in the required shape (circles, rectangles, ovals for the base layer) and bake at 150–160°C for 30–40 minutes. The surface should be dry and set; the interior should remain faintly chewy. This is the critical distinction from a fully baked meringue (which is dry throughout): dacquoise has a chewy centre even when correctly baked.
1. Nuts must be toasted before grinding — raw almonds or hazelnuts produce a flat, slightly bitter flavour. Toasted nuts produce a roasted-caramel complexity. 2. Grind to a fine meal, not a paste — if the nuts over-process, their oil is released and the meringue collapses 3. Fold nuts into meringue with a light hand — the same rule as any meringue-flour fold: preserve the air 4. Cool completely before use as an entremet base — a warm dacquoise is soft; a cooled one is firm Sensory tests: - **Surface dryness at the end of baking:** The surface of a correctly baked dacquoise should not be tacky when touched — it should peel cleanly from the parchment without sticking. - **Interior texture:** Break a piece — the interior should be faintly chewy, with a slight pull rather than a crumble. If it crumbles completely, it is over-baked. - **Smell during baking:** At the correct stage (approximately 25 minutes into baking), the kitchen should smell of toasted hazelnut and caramel — the nut sugars completing their Maillard reaction. If the smell is absent, the oven temperature is too low.
