Lemon Roll

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the batter

  1. Preheat the oven to 400°F (200°C).

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

  3. Add the milk, flour, and baking powder; mix until smooth.

Bake and fill

  1. Pour the batter into a small greased baking pan and bake for about 10‑15 minutes.

  2. Once baked, turn the cake out onto a clean surface and spread the cream on top immediately.

Make the cream

  1. For the cream, combine 1 cup sugar, the chopped lemon, and 1 egg in a saucepan.

  2. Cook over low heat until thickened, then let it cool before spreading on the rolls.

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

What each ingredient does

Eggs
Trap air when beaten with sugar and set the cake's structure as it bakes.
Sugar
Sweetens the batter and helps make the cake tender.
Flour
Provides the structure that holds the cake together for rolling.
Baking powder
Releases gas in the batter so the cake rises and stays light.
Milk
Adds moisture and softness to the batter.
Lemon
Adds acidity and bright citrus aroma to the cream.

The step that matters

Cook the cream over low heat. Eggs thicken as they heat, but high heat can scramble them and make the cream grainy. Gentle heat and cooling let the cream set smoothly for spreading.

Swap the lemon
