Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Layer Cream Cake
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
Preheat the oven to 400°F (200°C).
In a bowl, beat 6 eggs and 2 cups of sugar until well combined.
Add 2 tablespoons of water, 2 cups of flour, 2 teaspoons of cream of tartar, and 1 teaspoon of baking soda. Mix until smooth.
Pour the batter into a greased cake pan.
Bake for 20 minutes.
Let the cake cool.
Cut it in half.
Make the cream filling
Beat 2 eggs, 1 cup of sugar, and ⅓ cup of corn starch together.
Pour the mixture into 1 pint of boiling milk.
Stir until thickened.
Flavor the cream with the grated rind and juice of a lemon or 1 teaspoon of lemon extract.
Assemble
Spread the cream filling between the layers of the cake.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten into the batter to give the cake structure and help it rise.
- Flour
- Forms the cake's main structure once its proteins set in the oven.
- Cream of tartar
- Acidifies the batter so baking soda reacts and lightens the crumb.
- Baking soda
- Reacts with the acid in the batter to produce gas that makes the cake rise.
- Corn starch
- Thickens the boiling milk into a smooth, sliceable cream filling.
- Sugar
- Sweetens the cake and helps keep it tender and moist.
The step that matters
Pour the cream mixture into the boiling milk. Adding the egg and starch mixture to boiling milk too slowly, or stirring too little, can leave lumps or scrambled egg. Stirring steadily while pouring lets the starch thicken evenly and the eggs cook smoothly.
