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 ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the cream of tartar with the flour.
In another bowl, beat the egg yolks and whites separately.
Make the batter
Cream the butter, then add the dissolved baking soda to the milk.
Combine the butter mixture with the flour mixture, then fold in the beaten eggs.
Bake
Pour the batter into two square cake pans.
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake's shape as it bakes.
- Eggs
- Add structure and trapped air from the beaten whites, helping the cake rise.
- Butter
- Adds fat that makes the crumb tender and rich.
- Milk
- Supplies moisture that hydrates the flour and dissolves the baking soda.
- Baking soda
- Reacts with the acid in the cream of tartar to produce gas that leavens the batter.
- Cream of tartar
- Provides acidity that reacts with the baking soda to help the cake rise.
The step that matters
Folding in the beaten eggs. Beaten egg whites hold air bubbles that give the cake lift. Stirring them vigorously deflates the foam, so fold gently with a spatula until just combined, keeping the batter airy.
