Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Strawberry Sponge-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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, mix the egg yolks, sugar, milk, butter, baking powder, and enough flour to create a soft batter. Add lemon flavor to the batter.
Divide the batter into two shallow pans.
Bake the batter until done.
Assemble and finish
Spread strawberries on one cake layer.
Top the layer with beaten egg whites sweetened with powdered sugar.
Place the second cake layer on top.
Add more strawberries on the second layer.
Spread the remaining egg whites on top.
Return to the oven to brown, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help bind the batter while adding structure as it sets.
- Egg whites
- Beaten and sweetened, they form a light foam that adds lift and a glossy topping.
- Flour
- Forms the gluten and starch network that gives the cake its structure as it bakes.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Butter
- Adds fat for tenderness and a richer flavor in the crumb.
- Strawberries
- Add moisture and fruity sweetness between the layers.
The step that matters
Beating and topping the egg whites. Egg whites must be beaten to stiff, stable peaks with the powdered sugar. Underbeaten whites will weep or collapse, and overbaking them when browning can make them dry or rubbery.
