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 300°F (150°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 300°F (150°C).
Beat the butter and sugar together until creamy.
Make and bake the batter
Add the milk, flour, chopped walnuts, baking soda, cream of tartar, and vanilla extract, then mix well.
Gently fold in the beaten egg whites.
Pour the batter into a greased cake pan.
Bake for about 30-40 minutes or until a toothpick comes out clean.
Finish
Frost with chocolate frosting.
Top with additional chopped walnuts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to foam, they lighten the batter and give the cake an airy, tender crumb.
- Butter
- Creamed with sugar, it adds fat that gives the cake a rich, tender texture.
- Sugar
- Creamed with butter, it sweetens the cake and helps create a fine, even texture.
- All-purpose flour
- Provides the starch and gluten network that gives the cake its structure.
- Baking soda
- Reacts with acidic ingredients to produce gas that helps the cake rise.
- Cream of tartar
- An acid that stabilizes whipped egg whites and works with baking soda to aid rising.
The step that matters
Folding in the beaten egg whites. Stirring vigorously deflates the whipped whites and loses the air that lightens the cake. Gentle folding keeps the batter airy so it rises and stays tender.
