Common Jelly-roll Sponge

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

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

  2. In a large bowl, beat together the sugar and eggs until well combined.

  3. Gradually add the warm water while continuing to beat the mixture.

  4. In a separate bowl, mix the baking powder with the flour.

  5. Combine the flour mixture with the egg and sugar mixture until smooth.

Bake and roll

  1. Spread the batter onto parchment paper in a baking pan.

  2. Bake in the preheated oven until golden brown.

  3. Once baked, wet the paper, spread your jelly over the sponge, and roll it up carefully.

The flavor team

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.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Trap air and set into the sponge's structure as they heat.
Sugar
Sweetens the sponge and helps the beaten eggs hold air.
Flour
Forms the sponge's main structure as its starch sets during baking.
Baking powder
Releases gas when heated, making the sponge rise and stay light.
Warm water
Adds moisture and loosens the batter so it spreads evenly.

The step that matters

Combine the flour mixture with the egg and sugar mixture until smooth. Once flour is added, overbeating develops gluten and knocks out the air beaten into the eggs. The sponge then bakes tough and dense, and it may crack when rolled.
