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 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
Cream the butter and sugar together by hand.
Add 1 cup of flour, cream of tartar, and baking soda mixed in the milk.
Gradually add the remaining flour and beat until light.
Stir in the vanilla and chopped walnuts.
Bake
Pour the batter into a greased cake pan and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped or beaten egg whites add structure and lift to the cake.
- Butter
- Creamed with sugar, butter adds tenderness and richness to the crumb.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the acid in the cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acts as an acid that works with baking soda to help the cake rise and stabilize the batter.
- Walnuts
- Add texture and a toasty, nutty flavor to the crumb.
The step that matters
Gradually add the remaining flour and beat until light. Adding flour in portions keeps the batter smooth and well emulsified. Beating until light traps air that expands in the oven, so the cake rises evenly. Overmixing after the flour is fully in develops gluten, which can make the crumb tough.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar, butter, milk, flour, cream, vanilla):
- Almondfits better
