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. 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
Preheat the oven to 350°F (175°C).
Make the batter
Cream together the sugar and butter until light and fluffy.
Add the egg whites and mix well.
In a separate bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, alternating with the milk.
Fold in the walnut meats.
Bake
Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick comes out clean.

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 light, tender crumb and rich flavour.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed with butter.
- Egg whites
- Add structure and help the cake set as they cook.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Cream of tartar
- Stabilizes the egg whites and works with baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic ingredients to produce gas that lifts the batter.
The step that matters
Alternating the dry ingredients with the milk. Adding flour in portions alternated with liquid keeps the batter smooth and well combined. Adding it all at once can overwork the gluten and make the cake dense and tough.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, milk, cream, meat):
- Almondfits better
- Walnutthe original
- Pistachiofits about as well
- Chestnutfits about as well
Fit is the average pairing score against sugar, butter, flour, egg, milk, cream, meat. Candidates are from the same food group and used in at least 100 recipes.
