Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the cake layers
Preheat the oven to 350°F (175°C).
In a bowl, mix 1 cup sugar with the beaten egg yolks.
Sift in the baking soda and salt, then add the flour and cream of tartar.
Fold in the stiffly beaten egg whites.
Divide the batter into three shallow tins and bake until golden.
Make the lemon filling
For the lemon mixture, boil 1½ cups cold water, 1 cup sugar, and 2 teaspoons butter together.
Mix 1½ tablespoons cornstarch with a little cold water, then add to the boiling mixture.
Once thickened, stir in the beaten egg yolks, lemon juice, and grated rind.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake layers together as they bake.
- Eggs
- Egg whites add lift and structure, while yolks add richness and help set the filling.
- Baking soda
- Reacts with the acid in the batter to release gas, helping the layers rise.
- Cornstarch
- Thickens the boiling lemon mixture into a smooth, sliceable filling.
- Sugar
- Sweetens the cake and the lemon filling, balancing the tartness of the lemon.
- Lemon
- Its juice adds acidity and its grated rind adds bright aroma to the filling.
The step that matters
Stirring in the egg yolks. The cornstarch must be fully boiled to thicken the filling. Stir the beaten yolks in gently, since hot starch mixture can scramble yolks added too quickly, leaving the filling grainy.
