Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Cream Pie
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 batter
Cream together the sugar and butter, then beat in the milk and add the baking soda.
Mix in the flour and cream of tartar.
In a separate bowl, beat the egg yolks and whites separately.
Fold the beaten egg whites into the batter last.
Bake and fill
Bake in layer cake pans at 350°F (175°C).
For the filling, combine the grated chocolate, sugar, and a little milk in a saucepan.
Boil and thicken the mixture with flour.
Spread the filling between the baked layers.
Finish
Top with whipped cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites add lift and an airy structure to the batter, while yolks add richness.
- Butter
- Creamed with sugar, it traps air and gives the cake a tender, rich crumb.
- Flour
- Its proteins set during baking to give the cake its structure, and it thickens the chocolate filling.
- Baking soda
- Reacts with the acidity in the batter to produce gas that helps the cake rise.
- Cream of tartar
- An acid that stabilises the beaten egg whites and works with the baking soda to aid rising.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a light texture.
The step that matters
Folding in the beaten egg whites. Whites hold air only when whipped and gently folded; stirring hard deflates them, so the layers bake up flat and dense instead of light.
