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 ↓
Feather Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
Melt the butter in a bowl.
In another bowl, beat the eggs and add the milk.
Combine the egg mixture with the melted butter.
In a separate bowl, mix the flour, sugar, and baking powder, then sift into the butter and egg mixture.
Pour the batter into a greased cake tin.
Bake and ice
Bake in the preheated oven until done.
Once baked, mix the icing sugar with the egg white and pour over the top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure that sets the cake's crumb as it bakes.
- Eggs
- Bind the batter and add structure and richness to the crumb.
- Unsalted butter
- Adds fat for tenderness and a rich flavor in the crumb.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Granulated sugar
- Sweetens the cake and helps brown the crust while tenderizing the crumb.
The step that matters
Sifting the flour, sugar, and baking powder into the wet mixture. Sifting breaks up lumps and aerates the dry ingredients so they blend evenly. Uneven mixing can leave dense pockets or pockets of baking powder that affect rise and texture.
“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.
