Why it works: Vanilla and milk are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the cake
Sift the flour five times.
In a bowl, combine cream of tartar with egg whites and a pinch of salt.
Beat the egg whites until stiff peaks form.
Gently fold in the sifted flour, sugar, baking powder, and vanilla extract.
Pour the batter into a prepared cake pan and bake at 400°F (200°C) until done.
Once baked, cut the cake into three layers.
Make the filling
For the filling, combine ½ cup milk, sugar, and cornstarch with the beaten egg yolks.
Add this mixture to the remaining milk in a double boiler.
Cook until thick, stirring constantly.
Remove from heat and stir in butter and vanilla extract.
Assemble
Spread the filling between the cake layers and frost the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a foam that traps air, giving the cake its light, airy structure.
- Cream of tartar
- Acidifies the egg whites, helping the foam stay stable and hold its volume.
- All-purpose flour
- Provides the protein and starch that set the cake's structure as it bakes.
- Egg yolks
- Add richness and, when heated, help thicken the filling.
- Cornstarch
- Thickens the filling as it cooks, giving it a smooth, spreadable body.
- Butter
- Adds fat to the filling, contributing richness and a smoother mouthfeel.
The step that matters
Gently fold in the sifted flour. The cake's rise depends on the air trapped in the beaten egg whites. Folding gently keeps that air in the batter, while vigorous stirring deflates the foam and produces a dense, tough cake.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
