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 ↓
Walnut 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).
In a large bowl, cream together the sugar and butter.
Add the eggs and sweet milk, mixing well.
Make the batter
In a separate bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Pour the batter into prepared cake pans and bake until golden.
Assemble
For the filling, mix the powdered walnuts with sour cream and sweeten to taste.
Spread the walnut filling between the layers of cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Baking soda
- Reacts with the cream of tartar to release gas, helping the cake rise.
- Cream of tartar
- Acidifies the batter so it reacts with the baking soda to lighten the crumb.
- Flour
- Forms the main structure that holds the cake together as it bakes.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Walnut meats
- Provide nutty flavor and body to the powdered walnut filling.
The step that matters
Gradually add the dry ingredients to the wet mixture, stirring until smooth.. Adding flour in portions and stirring only until smooth keeps gluten development controlled, so the cake stays tender rather than tough, and the batter mixes evenly.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, flour, milk, egg, cream, meat):
- Almondfits better
- Walnutthe original
- Pistachiofits about as well
- Chestnutfits about as well
Fit is the average pairing score against sugar, butter, flour, milk, egg, cream, meat. Candidates are from the same food group and used in at least 100 recipes.
