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 ↓

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).
Combine eggs, sugar, melted butter, salt, milk or water, and cream of tartar in a mixing bowl.
Beat the mixture well.
Sift flour and baking soda together twice.
Add the sifted flour and baking soda to the egg mixture.
Stir until smooth.
Pour the batter into a greased dripping pan.
Bake and roll
Bake until golden.
Remove the cake from the oven.
Turn the cake onto a sheet of paper sprinkled with powdered sugar.
Spread the jelly evenly over the cake.
Roll the cake up tightly using the paper to help shape it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked into the batter, they provide structure and lift for a light, rollable sponge.
- Granulated sugar
- Sweetens the cake and helps give it a tender crumb.
- All-purpose flour
- Forms the structure that holds the sponge together while it rolls.
- Cream of tartar
- Stabilises the beaten egg mixture and helps it keep its airy texture.
- Baking soda
- Reacts with the acid in the batter to add lift and help the cake rise.
- Jelly
- Adds moisture and sweet fruit flavour inside the rolled cake.
The step that matters
Rolling the cake while warm. A sponge that is rolled too late cracks and tears, because it stiffens as it cools. Rolling it promptly while still warm, with the paper supporting it, lets the crumb bend without breaking.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
