Why it works: Butter and milk 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 ↓
Reliable Sponge Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Sift in the flour and baking powder, then mix well.
Pour in the milk and add lemon flavoring.
Gently fold in the well-beaten egg whites.
Bake and assemble
Pour the batter into jelly pans.
Bake until golden brown.
Spread grated coconut and powdered sugar between layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Well-beaten egg whites trap air, giving the sponge its light, airy structure.
- All-purpose flour
- Provides the starch and structure that sets the cake's crumb as it bakes.
- Baking powder
- Releases gas during baking, helping the batter rise and become tender.
- Butter
- Creaming with sugar traps air and adds richness and a tender texture.
- Sugar
- Sweetens the cake and helps create a soft, fine crumb when creamed.
- Milk
- Adds moisture and liquid that hydrates the flour to form the batter.
The step that matters
Gently fold in the well-beaten egg whites. Folding rather than stirring keeps the air bubbles in the whites intact. Those bubbles give the sponge its lift, so overmixing will leave the cake dense.
