Why it works: Butter and milk 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 ↓
Neaponitan 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Mix the corn starch and flour together.
Make the batter
In a large bowl, cream the butter and sugar until light and fluffy.
Add the milk and mix well.
Gradually add the flour and corn starch mixture.
Fold in the beaten egg whites gently until combined.
Pour the batter into a greased cake pan.
Bake
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten stiff, they trap air and give the cake its light, airy structure.
- Butter
- Creamed with sugar, it traps air and adds richness and tenderness to the crumb.
- Flour
- Provides the main structure that sets as the cake bakes.
- Corn starch
- Softens the crumb by diluting gluten, giving a finer, more tender texture.
- Sugar
- Creamed with butter to aerate the batter and adds sweetness and browning.
- Cream of tartar
- Stabilizes the beaten egg whites so they hold their volume during folding and baking.
The step that matters
Fold in the beaten egg whites gently. Egg whites hold air only when beaten stiff. Overmixing or stirring vigorously knocks out that air, so the cake bakes up dense instead of light.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
