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 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 cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the beaten egg whites and sweet milk, mixing well.
Sift together the flour, corn starch, and baking powder; fold into the mixture.
Pour the batter into prepared cake pans and bake until golden.
Make the frosting and finish
For the frosting, boil 2 cups of sugar and ½ cup of water until it spins a thread or forms a soft ball in cold water.
Pour the hot syrup over the beaten egg whites and beat until cool.
Spread the frosting between the layers and on the top and sides of the cake.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Egg whites
- Whipped foam that gives the cake its light, airy crumb and lift.
- Butter
- Fat that softens the crumb and adds richness to the cake.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Corn starch
- Lightens the crumb by partly replacing flour, giving a tender texture.
- Baking powder
- Releases gas during baking so the cake rises and stays light.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
The step that matters
Cooking the frosting syrup to the right stage. The syrup must reach the thread or soft-ball stage, because its sugar concentration sets how the frosting firms as it cools. Pouring it over beaten whites while hot then beating until cool lets the whites trap air and form a stable, glossy frosting.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
