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 ↓
Cream Sponge Pie
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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs and sugar until light and fluffy.
Sift the flour and baking powder together, then gradually add to the egg mixture.
Stir in the sweet milk until well combined.
Bake and assemble
Pour the batter into pie pans and bake until golden and a toothpick comes out clean.
Once baked, split the sponge cake and spread 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
- Whipped with sugar to trap air, giving the sponge its light, airy structure.
- Flour
- Provides the starch and gluten framework that sets the cake's crumb as it bakes.
- White sugar
- Sweetens the cake and helps the beaten eggs hold their foam.
- Sweet milk
- Adds moisture to the batter, loosening it and keeping the crumb tender.
- Baking powder
- Releases gas in the oven, helping the sponge rise and become light.
The step that matters
Beating the eggs and sugar until light and fluffy. This step builds the air foam that lifts the sponge. If the eggs are under-beaten, the batter stays dense and the cake rises poorly. Folding in the flour gently keeps that air from collapsing.
