Ingredients
Directions
Prepare
Make three thick layers of cake: one gold flavored with lemon and two silver with almond.
In a double boiler, heat the milk or cream.
Add the beaten egg yolks and arrowroot.
Cook until thickened, then divide into two parts.
Flavor the custard
To one part, add powdered sugar, grated chocolate, and crushed macaroons or coconut.
To the second part, add bitter and sweet almonds, sliced citron, powdered sugar, and rose water.
Color the second part with cochineal.
Assemble and ice
Assemble the cake: layer a white cake with chocolate cream, then a yellow cake with rose cream, and top with a white cake.
For the icing, beat the egg whites with powdered sugar.
Gradually add the almond paste mixed with rose water to the icing.
Finish with a plain white icing over the top and sides.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they cook and add richness to the cream filling.
- Arrowroot
- Thickens the milk mixture into a smooth, sliceable custard without making it cloudy.
- Milk or cream
- Provides the liquid base and moisture for the custard filling.
- Egg whites
- Whipped with sugar, they give the icing body and help it set firm.
- Powdered sugar
- Sweetens the fillings and icing and dissolves smoothly for a fine texture.
- Almonds
- Add nutty flavor and a firm texture to the rose cream filling.
The step that matters
Cook the custard until thickened. Heat must be gentle and steady in the double boiler. Egg yolks can curdle if overheated, while arrowroot only thickens fully once it is heated, so the custard needs stirring and patience.
