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 ↓
Cornstarch 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 your oven to 350°F (175°C).
Make the batter
In a large bowl, beat the egg whites until stiff peaks form.
In another bowl, cream the butter and powdered sugar together until light and fluffy.
Add the milk and mix well.
Sift together the cornstarch, cream of tartar, and baking soda, then gradually add to the butter mixture.
Fold in the beaten egg whites gently.
Add lemon flavoring to taste.
Bake
Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick 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
- Whipped to stiff peaks, they trap air and lighten the cake's texture.
- Cornstarch
- Provides a tender, fine crumb with less gluten structure than flour.
- Butter
- Creamed with sugar to add richness and a soft, tender texture.
- Powdered sugar
- Sweetens the batter and helps create a light, fluffy creamed base.
- Cream of tartar
- Stabilizes the whipped egg whites, helping them hold their peaks.
- Baking soda
- Reacts with the acidity in the batter to help the cake rise.
The step that matters
Folding in the beaten egg whites. Stirring vigorously deflates the whipped foam that gives the cake its lift. Fold gently with a spatula so the air bubbles stay trapped in the batter while it bakes.
Swap the lemon

Fit is the average pairing score against egg, milk, sugar, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
