Why it works: Butter and walnut are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 6,832 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. 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
In a bowl, cream together the butter and sugar until light and fluffy.
Add the baking powder and mix well.
Fold in the walnut kernels.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the walnut mixture.
Bake
Pour the batter into a small-sized pan, similar to an almond sponge cake.
Bake until golden brown and a toothpick inserted comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and add richness and a tender crumb.
- Sugar
- Creams with butter for a light texture and adds sweetness and browning.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Egg whites
- Whipped to stiff peaks, they add air and structure for a light cake.
- Walnut kernels
- Add texture, nutty flavor, and fat that keeps the crumb moist.
The step that matters
Gently fold the egg whites into the walnut mixture.. Whipped egg whites hold air that makes the cake light. Stirring vigorously or overmixing knocks that air out, leaving a dense result.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, egg):
- Almondfits better
- Pecansfits better
- Filbertfits about as well
- Walnutthe original
Fit is the average pairing score against sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
