Why it works: Milk and butter 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 ↓
French Cream Cake
Ingredients
Directions
Make the cream filling
Boil the sweet milk in a saucepan.
Dissolve the corn starch in a little milk and set aside.
In a bowl, combine the egg whites, egg yolk, and sugar.
Once the milk boils, slowly pour in the corn starch mixture while stirring continuously until thickened.
Remove from heat and stir in the butter.
Make and assemble the cake
For the cake, beat the eggs and mix with sugar, flour, baking powder, and cold water.
Bake the cake in layers until golden.
Spread the cream filling between the layers and flavor to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and moisture, and help the cake set and hold its layers.
- Corn starch
- Thickens the milk mixture into a smooth cream filling as it heats.
- Flour
- Forms the structure that holds the cake's crumb together.
- Baking powder
- Releases gas in the batter so the cake rises and becomes lighter.
- Butter
- Adds fat for richness and a tender texture in the cream filling.
- Sugar
- Sweetens the cake and cream, and helps keep the crumb tender.
The step that matters
Pouring the corn starch into the boiling milk. Stirring constantly while pouring in the starch keeps it dispersed so it does not form lumps or scorch on the base. The starch thickens as it heats, so the cream sets smoothly.
