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 Loaf 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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix the powdered sugar, sour cream, and baking soda.
Stir in the chopped nuts and flour until well combined.
If using sour milk, add the butter to the mixture.
Bake and finish
Pour the batter into a loaf pan and bake until golden.
Let cool and frost with plain icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the loaf together as it bakes.
- Sour cream
- Adds moisture and tenderness, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the sour cream's acidity to release gas that helps the loaf rise.
- Powdered sugar
- Adds sweetness and helps give the crumb a fine, tender texture.
- Chopped nuts
- Adds texture and a toasty, rich flavor to the crumb.
The step that matters
Stir just until combined. Once flour is added, overmixing develops gluten, which toughens the crumb. Stir only until the flour is incorporated so the loaf stays tender.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, cream, flour, butter, milk):
- Almondfits better
- Pistachiofits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against sugar, cream, flour, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
