I mentioned this Gateau Choco-Citron about two posts ago and told you I made up the recipe on the fly, so here I am sharing that recipe with you. It's a three-layered cake made of a rich chocolate brownie layer, a sweet, tart lemon curd layer, topped with a soft chocolate mousseline layer. Thanks once again to Aube of Kitchen Vignettes for describing the components of this gateau so well that I was able to make it in my very own kitchen one afternoon.
