Why it works: Olive and walnut match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,087 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
Sponge Cake with Olive Oil
Ingredients
Directions
Prepare
Preheat oven to 350°F.
Butter the sides of a 9‑inch diameter cake pan and line the base with a circle of baking parchment.
Make the batter
Using an electric mixer, beat eggs until combined and gradually add sugar, beating until light and fluffy, about 2 minutes.
Pour olive oil and wine around the edge of the bowl and fold in with a rubber spatula.
Sift together flour, baking powder, and salt, and fold into the egg mixture.
Fold in the walnuts and the chocolate chips.
Bake and cool
Spoon batter into the prepared pan and bake until a toothpick can be inserted and pulled out clean, about 40 minutes.
Remove cake from oven, let stand for 10 minutes in pan, then turn out onto a cooling rack.
Peel off paper, turn cake right side up, and allow to cool completely.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped with sugar to trap air, giving the cake its light, airy structure.
- All-purpose flour
- Forms the gluten network and sets the crumb structure as the cake bakes.
- Baking powder
- Releases gas during baking, helping the cake rise and become tender.
- Olive oil
- Adds moisture and fat, keeping the crumb soft and tender.
- Sugar
- Adds sweetness and helps hold air in the whipped eggs while contributing to browning.
The step that matters
Folding in the flour and walnuts. Folding gently keeps the air beaten into the eggs. Overmixing develops too much gluten, which can make the cake dense and tough.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar, olive, flour, chocolate):
- Almondfits better
- Hazelnutfits better
- Chestnutfits about as well
- Walnutthe original
Fit is the average pairing score against egg, sugar, olive, flour, chocolate. Candidates are from the same food group and used in at least 100 recipes.
