Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Walnut Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar until very light.
Add the chopped walnuts and vanilla.
Slowly mix in the milk.
Sift together the flour, baking powder, and salt, then add to the mixture.
Beat all ingredients together until light.
Bake
Gently fold in the stiffly beaten egg whites.
Bake in a moderate oven at 350°F (175°C) for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Stiffly beaten whites give the cake lift and an airy, light crumb when folded in.
- Butter
- Creaming with sugar traps air and adds richness and a tender texture.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Fine sugar
- Sweetens the cake and helps create a light, tender texture when creamed.
The step that matters
Folding in the egg whites. Stirring too vigorously knocks out the air whipped into the egg whites, leaving a dense cake. Fold gently so the batter stays light and rises well.
Swap the walnut
How well each one fits the dish's main ingredients (butter, sugar, milk, flour, vanilla, egg):
- Almondfits better

Fit is the average pairing score against butter, sugar, milk, flour, vanilla, egg. Candidates are from the same food group and used in at least 100 recipes.
