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 ↓
A Delicate Cake for Tra
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Beat the yolks and whites of the eggs separately.
Add sugar and milk to the yolks, then mix in the creamed butter.
Fold in the beaten egg whites.
Sift the flour with baking soda and cream of tartar, then add to the mixture.
Bake
Pour into shallow pans and bake at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air for lift, while yolks add richness and structure.
- Flour
- Forms the structure that holds the cake's airy crumb once baked.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Butter
- Adds fat for tenderness and a softer, richer crumb.
- Baking soda
- Reacts with acid in the batter to release gas and help the cake rise.
- Cream of tartar
- Acidic ingredient that reacts with baking soda and stabilizes the egg whites.
The step that matters
Folding in the beaten egg whites. Stirring too hard or too long knocks out the air trapped in the whites, so the cake rises less and turns dense. Fold gently with a spatula until just combined.
