Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Feather Cake
Ingredients
Directions
The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together in a bowl.
Add the milk and beat until combined.
Beat the eggs well, then add them to the mixture, beating again.
Combine the baking powder and salt with the flour, then beat this into the batter.
Add the vanilla and lemon extracts last and mix well.
Bake
Pour the batter into a well‑greased pan and sprinkle the top with powdered sugar.
Bake in a moderate oven at 350°F (175°C) until golden.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich texture.
- Sugar
- Sweetens the cake and helps hold air when creamed with butter.
- Eggs
- Add structure and richness to the batter as they set in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Milk
- Adds moisture and loosens the batter to a smooth consistency.
The step that matters
Beating in the flour mixture. Once flour is added, overmixing develops gluten and can make the cake tough and dense, so mix only until the flour is just incorporated.
