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.
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the milk and beaten eggs, mixing well.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the chopped walnuts.
Bake and finish
Pour the batter into a loaf pan and bake at 350°F (175°C) until a toothpick comes out clean.
Ice with plain boiled frosting once cooled.

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
- Butter
- Creams with the sugar to trap air, giving the cake a light, tender crumb and rich flavor.
- Eggs
- Bind the batter and add structure while helping the cake set as it bakes.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter so the cake rises and becomes airy.
- Walnut meats
- Add texture and a nutty flavor, and flour-dredging helps them stay suspended in the batter.
The step that matters
Stirring the dry ingredients into the wet mixture. Stirring only until just combined keeps gluten development low, so the cake stays tender rather than tough and dense.
Swap the walnut
How well each one fits the dish's main ingredients (butter, sugar, milk, egg, flour, meat):
- Almondfits better
- Walnutthe original
- Pecansfits about as well
- Chestnutfits about as well
Fit is the average pairing score against butter, sugar, milk, egg, flour, meat. Candidates are from the same food group and used in at least 100 recipes.
