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 ↓
Marshmallow 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the dissolved corn starch and sweet milk, mixing well.
Sift the flour with baking powder and gradually add to the mixture.
In a separate bowl, beat the egg whites until stiff peaks form, then fold them into the batter.
Bake
Divide the batter into three layers and bake until golden.

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 give the cake its light, airy structure.
- Flour
- Forms the main structure that sets the cake as it bakes.
- Baking powder
- Releases gas during baking, helping the layers rise and become tender.
- Butter
- Creamed with sugar, it adds richness, tenderness and flavor to the crumb.
- Corn starch
- Softens the crumb and helps it stay moist and tender.
The step that matters
Folding in the egg whites. Stiff whites hold the batter's air, so folding gently rather than stirring keeps the cake light. Overmixing deflates the foam and produces a dense layer.
