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 ↓
Two-pound Cake By Measure
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).
Make the batter
In a large bowl, beat the egg whites until stiff peaks form.
In another bowl, cream together the butter and sugar until light and fluffy.
Gradually add the flour and milk to the butter mixture, mixing well.
Fold in the beaten egg whites and cream of tartar gently.
Bake
Pour the batter into a warm pan and bake until golden brown.

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 that lifts the cake's crumb.
- All-purpose flour
- Provides the starch and gluten that build the cake's structure.
- Granulated sugar
- Creams with the butter for a light texture and adds sweetness and browning.
- Butter
- Adds fat for tenderness and rich flavor.
- Sweet milk
- Supplies moisture that hydrates the flour and loosens the batter.
- Cream of tartar
- Stabilizes the whipped egg whites so they hold their peaks.
The step that matters
Fold in the beaten egg whites gently. Vigorous stirring knocks air out of the whipped whites, which deflates the batter and leaves a dense cake instead of a light one.
“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.
