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 ↓
Nut 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter until light and fluffy.
Add the milk and mix well.
Gradually stir in the flour and baking powder.
Fold in the egg whites and nuts until just combined.
Pour the batter into a greased cake pan.
Bake and frost
Bake for 30-35 minutes or until a toothpick comes out clean.
For the frosting, mix the sour cream, sugar, and chocolate until smooth.
Spread the frosting over the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and add richness and tenderness to the crumb.
- Flour
- Forms the structure of the cake once the batter sets in the oven.
- Egg whites
- Add structure and help bind the batter while adding lightness.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Sugar
- Adds sweetness and helps the batter brown and stay moist.
- Sour cream
- Adds moisture and a slight tang to the frosting.
The step that matters
Folding in the egg whites and nuts. Overmixing knocks air out of the whipped structure and toughens the batter, so the cake comes out dense. Stop as soon as the ingredients are just combined.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, egg, cream, chocolate):
- Almondfits better
- Hazelnutfits better
- Pistachiofits better
- Nutsthe original
Fit is the average pairing score against sugar, butter, milk, flour, egg, cream, chocolate. Candidates are from the same food group and used in at least 100 recipes.
