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 ↓
Yellow Mountain Cake
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
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and powdered sugar until light and fluffy.
Add the egg yolks and mix well.
Stir in the sweet milk and flour, then beat until smooth.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Add the baking soda and cream of tartar, mixing until well combined.
Bake and fill
Pour the batter into greased jelly cake tins.
Bake until a toothpick inserted in the center comes out clean.
For the filling, beat the egg whites until stiff, then gradually add the sugar and a pinch of tartaric acid, mixing well.
Spread the filling between the cooled cakes.

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 to the batter.
- All-purpose flour
- Forms the gluten network that gives the cake its structure once baked.
- Butter
- Creamed with sugar to trap air and add tenderness and richness.
- Powdered sugar
- Sweetens the cake and helps create a fine, light texture when creamed with butter.
- Baking soda
- Reacts with the acid in the batter to release gas that makes the cake rise.
- Cream of tartar
- Acidic component that stabilizes whipped egg whites and works with the baking soda to aid rising.
The step that matters
Folding in the egg whites. Whipped whites are full of trapped air. Stirring them in vigorously deflates the foam and makes the cake dense, so fold gently with a spatula until just combined.
