What is the name of a baked meringue layer that incorporates chopped nuts before shaping and baking?

The baked meringue layer that incorporates chopped nuts before shaping and baking is known as Japonais. This delightful meringue-based dessert is typically made with almond or hazelnut flour, which contributes to its unique texture and flavor. The process involves whipping egg whites to a stable peak and carefully folding in the nut flour, sometimes along with sugar, to maintain aeration. After the mixture is piped or spread into shapes, it is baked until it achieves a light, crispy exterior while remaining soft on the inside. Japonais is often used as a component in layered desserts or served with cream and fruit, showcasing the rich flavor that the nuts provide.

In contrast, macarons are almond meringue confections filled with ganache, buttercream, or jam, but they are not typically made into a thick layer for traditional pastry structures. Angel food cake is a light, airy cake made primarily of egg whites and does not contain nuts or meringue layers in the same manner. Pavlova is a dessert consisting of a crisp meringue shell filled with whipped cream and fruit, which serves a different purpose from the layered texture of Japonais.
