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 ↓
Twin Gold 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.
Make the batter
Cream the butter and sugar until very light and white.
Beat the egg yolks separately for a few minutes, then stir them into the creamed mixture.
Add the sweet milk, then the flour and baking powder, stirring lightly until the flour disappears.
Bake
Pour the batter into an ungreased angel cake mold.
Bake in a moderate oven at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks add richness, structure and a golden color to the batter.
- Butter
- Creaming with sugar traps air and gives the cake a tender, fine crumb.
- Flour
- Forms the gluten network that gives the cake its set structure.
- Baking powder
- Releases gas in the oven, helping the cake rise and turn light.
- Granulated sugar
- Sweetens the cake and helps trap air when creamed with the butter.
The step that matters
Stirring the flour in lightly. Overmixing once the flour is added develops too much gluten, which makes the cake tough and dense instead of tender.
