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 ↓
Cream Pie
Ingredients
Directions
Make the filling
Beat 2 eggs, 1 cup sugar, and 2 tablespoons corn starch together.
Boil 1 pint milk and season with vanilla.
Just as the milk boils, stir in the egg mixture continuously until it thickens.
Before cooking, stir in 1 tablespoon butter for the pie filling.
Make and bake the cake
For the cake, beat 3 eggs with 1 cup sugar and ¼ teaspoon baking soda in ½ cup sour cream.
Mix in 1 teaspoon cream of tartar and 1½ cups flour.
Bake quickly in jelly cake pans.
Assemble
When cold, slice the cake and layer it with the cream filling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they heat and give the cake structure as they bind the batter.
- Corn starch
- Thickens the milk mixture into a smooth, sliceable cream filling as it heats.
- Milk
- Forms the liquid base of the cream filling, which thickens when heated with the eggs and starch.
- Flour
- Provides the main structure of the cake once it sets in the oven.
- Baking soda
- Reacts with the acid in the sour cream and cream of tartar to lift the cake.
- Sour cream
- Adds moisture and acidity to the cake batter, tenderising the crumb and helping it rise.
The step that matters
Stir the egg mixture into the boiling milk. Stir continuously as it thickens. Constant stirring spreads the heat so the eggs do not curdle or scorch, and the starch thickens smoothly without lumps.
