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 ↓

Sponge Roll

Oven, in the book's wordsA warm oven

Ingredients

Directions

The book says “a warm oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the batter

  1. In a bowl, break the eggs and fill a teacup with sweet cream.

  2. Add a little salt and flavoring, then beat until light.

  3. Gradually add sugar and flour, mixing well.

  4. Pour the batter into loaf or jelly tins.

Bake and serve

  1. If using jelly tins, fill with marmalade, preserves, or chocolate filling.

  2. Bake until golden and serve with sauce.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Whipped into the batter to trap air, giving the cake its light, airy structure.
Flour
Provides the structure that holds the cake's crumb once it is baked.
Sugar
Sweetens the cake and helps it brown as it bakes.
Baking powder
Releases gas during baking, helping the batter rise and become lighter.
Sweet cream
Adds moisture and richness to the batter, softening the crumb.

The step that matters

Beating the eggs until light. Beating incorporates air into the eggs, which is what lifts a sponge. Under-beaten batter bakes dense, while over-mixing once flour is added can toughen the crumb.
