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 ↓
White 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
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, cream the butter and sugar together until light and fluffy.
Add the egg whites and mix well.
Dissolve the baking soda in the milk and add it to the mixture.
Sift together the flour and cream of tartar, then gradually add to the wet ingredients. Mix until just combined.
Bake
Pour the batter into a greased cake pan and bake 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
- Butter
- Fat that creams with sugar to trap air, giving a tender crumb and rich flavor.
- Sugar
- Creams with butter to hold air, and adds sweetness and gentle browning.
- Egg whites
- Set as the cake bakes to build structure, and add moisture.
- Flour
- Its proteins set in the oven to form the cake's structure.
- Baking soda
- Reacts with the acid in cream of tartar to release gas, helping the cake rise.
- Cream of tartar
- Provides the acid that reacts with baking soda to help the cake rise.
The step that matters
Mix until just combined. Once flour is added, mixing develops gluten. Overmixing makes the cake tough and dense, so stop as soon as the batter is smooth.
