Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Sponge Cream Pie
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 crust
Preheat the oven to 400°F (200°C).
Make the crust for two pies: In a bowl, beat 3 eggs and mix in 1 cup of sugar.
In another bowl, combine 1½ cups of flour and 2 teaspoons of baking powder.
Add the flour mixture to the egg and sugar mixture, then stir in ½ cup of cold water.
Finally, add 1 tablespoon of hot water and mix well.
Pour the batter into deep pie pans and bake immediately.
Make the cream
While the pies cool, prepare the cream: In a tin bucket, combine 1 cup of water and ½ cup of milk.
Place the bucket in a kettle of cold water and heat until the water boils.
In a separate bowl, beat 1 egg and mix in ½ cup of sugar.
Add 1 tablespoon of flour or cornstarch mixed with a little cold milk to the egg mixture.
Pour this mixture into the boiling milk and water, stirring until it thickens.
Flavor the cream to taste and let it cool partially before spreading between the pie layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs build the airy structure of the sponge batter and set the crust as it bakes.
- Baking powder
- Releases gas in the batter, helping the sponge rise and become light in the oven.
- Flour
- Provides the starch and protein that set the crust, and thickens the cream as it heats.
- Milk
- Adds richness and moisture to the cream and helps it set smoothly when heated.
- Sugar
- Sweetens the batter and cream and helps give the sponge a tender crumb.
The step that matters
Pour the cream mixture into the boiling milk and stir until it thickens. Adding the egg and starch mixture to boiling liquid while stirring keeps it smooth; the starch swells and thickens as it heats, and stopping the stirring or heating too little can leave lumps or a thin cream.
