Meringue Based Sponge Example : Dacquoise
The dacquoise is a meringue-based sponge which falls under different names depending upon the variety of nut used. With almonds, a Dacquoise; with hazelnuts, a Japonaise, and a Progres with half of each! Very often unconventional ingredients such as sesame seeds or coconut lend themselves to the basic technique. These layers work very well with nearly all types of fillings, creams, and frostings.
A dacquoise is nutty, airy, has a slight chewiness and a delicate crispy exterior. Much like a macaron, it is also made by folding finely ground nuts and sugar through a meringue. The dacquoise provides lightness to desserts and a nice alternative to a classic or separated sponge, providing a more interesting texture and flavor as well as an opportunity for gluten-free layers.
The almond dacquoise is the classic version of dacquoise, but feel free to be creative in dry additions. Simply replace a portion of the ground nut component with a similar size and texture. Desiccated coconut, various nut meals, even seeds can create interesting textures and flavors.
Sugar 2.5 ounces (70gr)
Egg Whites 7 each (200gr)
Confectioners Sugar 7 ounces (200gr)
Almond Flour 6.5 ounces (180gr)
Preheat the oven to 360°F. Line sheet pans with parchment and fit a 1/2 inch plain piping tip to a pastry bag.
Sift the nut meal and confectioners sugar at least twice through to aerate. If there are large particles of nuts, a food processor may be helpful; be careful not to grind to a paste.
In the bowl of a stand mixer with a whisk attachment, beat the egg whites on moderate speed until soft peak. Lower the speed and gradually add the sugar, continuing to beat until dissolved. Raise the speed to moderate-high and beat until firm peak. Take care not to over-whip the meringue.
Transfer the meringue into a large bowl. Again sift the nut mixture over the meringue and fold, being careful to not deflate the batter.
Pipe the mixture or spread with an offset spatula onto a lined baking sheet.
Bake until the middle is golden brown.
Allow to cool completely at room temperature before use or wrapping for freezer storage (up to 3 months).
