Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make and bake the batter
In a bowl, beat the eggs and sugar until light and fluffy.
Gently fold in the flour, baking soda, and cream of tartar.
Spread the batter thinly onto greased bread pans.
Bake in the preheated oven until golden brown.
Fill and roll
Remove from the oven, spread jelly over the top, and roll up the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whip air into the batter and provide structure for a light, sponge-like crumb.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Sugar
- Adds sweetness and helps the beaten eggs hold their airy texture.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Cream of tartar
- Acidic ingredient that reacts with baking soda to help the cake rise and stay tender.
The step that matters
Folding in the flour, baking soda, and cream of tartar. Folding gently keeps the air beaten into the eggs. Overmixing deflates the batter, so the thin cake may turn out dense and fail to roll cleanly.
