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
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
Preheat the oven to 350°F (175°C).
Beat together 1 cup of sugar and 3 eggs until very light.
Sift together 1¾ cups of flour and 2 teaspoons of baking powder several times.
Gradually mix the flour into the egg mixture.
Add 4 tablespoons of boiling water.
Pour the batter into two cake pans.
Bake until golden.
Make the cream
For the cream, heat 1 pint of milk until nearly boiling.
Mix 2 tablespoons of cornstarch with a little cold milk.
Add to the hot milk.
Beat 2 eggs with 1 cup of sugar.
Combine with the milk mixture.
Stir constantly while cooking until it thickens enough to drop from a spoon.
Remove from heat.
Stir in ½ cup of melted butter and your choice of flavoring.
Assemble
Once the cakes are cool, split them with a sharp knife.
Spread the cream between the layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten with sugar to trap air, giving the cake structure and a light crumb.
- All-purpose flour
- Provides the starch and gluten network that gives the cake its main structure.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Milk
- Forms the base of the cream, which is thickened by cooking with cornstarch and egg.
- Cornstarch
- Thickens the cream as it heats, giving it a spreadable body.
- Butter
- Adds richness and a smooth, silky texture to the finished cream.
The step that matters
Stir the cream constantly while it cooks. Egg and cornstarch thicken the cream, but the egg can scramble and lumps can form if the mixture sits still over heat. Constant stirring keeps it smooth and evenly thickened.
