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 ↓
Feather Cake
Ingredients
Directions
The book says “a rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Soften the butter without melting it.
Beat the butter with the sugar and egg until well combined.
Add the milk and mix well.
In a separate bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture.
Bake
Pour the batter into shallow pans.
Bake in a 400°F (200°C) oven for 30 minutes.

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 together as it sets.
- Egg
- Adds structure and binds the batter while helping it set in the oven.
- Baking soda
- Reacts with the acid in the cream of tartar to produce gas that lifts the cake.
- Cream of tartar
- Acts as an acid that works with the baking soda to help the cake rise.
- Butter
- Adds fat for tenderness and flavor in the crumb.
- Sugar
- Sweetens the cake and helps give it a tender texture and golden browning.
The step that matters
Gradually add the dry ingredients to the wet mixture.. Adding flour in portions and mixing gently keeps the batter smooth and limits gluten development, which would otherwise make the cake tough and dense.
