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 ↓
Ice Cream Cakes
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
Cream the butter and 2 cups of sugar together until light and fluffy.
Add the sweet milk, flour, and baking powder.
Fold in the beaten egg whites.
Divide the batter into jelly-cake pans and bake at 350°F (175°C) until golden.
Make the icing
For the icing, boil 8 cups of sugar with 1 cup of boiling water until it forms a thick syrup.
Pour the hot syrup over the beaten egg whites while stirring until cool.
Add citric acid and flavor with lemon or vanilla.
Assemble
Spread the icing between and on top of the layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cake a tender, rich crumb.
- Flour
- Forms the structure that holds the cake's shape as it bakes.
- Baking powder
- Releases gas in the batter, making the layers rise and turn light.
- Egg whites
- Beaten and folded in, they add lift and a light, airy texture.
- White sugar
- Sweetens the cake and, when boiled, forms the thick icing syrup.
The step that matters
Pouring the hot syrup over the egg whites while stirring. The hot sugar syrup cooks the beaten whites into a stable, glossy icing. Pouring slowly while stirring keeps the whites from scrambling and helps the icing thicken as it cools.
Swap the lemon

Fit is the average pairing score against sugar, butter, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
