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 ↓
White Mountain Jelly 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 large bowl, combine butter and sugar, then mix in flour and milk.
Add eggs, cream of tartar, and baking soda (dissolved in milk).
Stir all ingredients together without separating the eggs.
Bake
Pour the batter into a prepared cake pan and bake until golden.
Frost and assemble
For frosting, beat the egg whites and gradually add fine white sugar until stiff peaks form.
Spread frosting between layers of the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure that holds the cake's crumb together as it bakes.
- Eggs
- Add structure and binding, helping the batter hold together and set in the oven.
- Butter
- Adds fat that tenderizes the crumb and contributes richness and flavor.
- Sugar
- Sweetens the cake and helps it brown while keeping the crumb tender.
- Baking soda
- Reacts with the acid in the batter to release gas that helps the cake rise.
- Cream of tartar
- Provides acidity that reacts with baking soda to help the cake rise.
The step that matters
Beating the egg whites for the frosting. Adding sugar gradually while beating lets the whites form a stable foam. Adding it all at once or overbeating can leave the frosting grainy, soft, or collapsed, so stop when stiff peaks form.
