Fancy Sponge Roll

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 bowl, beat the eggs and sugar until light and fluffy.

  3. Add the softened butter and mix well.

  4. Sift in the flour and baking powder, then fold gently.

  5. Add cochineal to color the mixture pink.

  6. Pour the batter into a greased oblong sandwich tin (about 18 x 10-12 inches).

Bake and roll

  1. Bake until lightly golden and not too thick.

  2. Turn the sponge out onto a sheet of paper dusted with icing sugar.

  3. Spread a good filling over the sponge and roll it up while hot.

Ice and decorate

  1. Ice the roll with your choice of flavored icing.

  2. Decorate with icing tubes, cut preserved cherries, and angelica.

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

What each ingredient does

Eggs
Whisked with sugar to trap air, giving the sponge its light structure.
Butter
Adds richness and a tender crumb to the sponge.
Sugar
Sweetens the batter and helps whip air into the eggs for lightness.
All-purpose flour
Forms the sponge's structure once set by heat.
Baking powder
Releases gas in the batter, helping the sponge rise.

The step that matters

Turn the sponge out and roll it while hot. A hot sponge is pliable, so it can be rolled without cracking. Once it cools, the structure stiffens and the roll is likely to split.

Swap the angelica

How well each one fits the dish's main ingredients (egg, butter, sugar, flour, chocolate):

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Jalapenofits better
  4. Angelicathe original

Fit is the average pairing score against egg, butter, sugar, flour, chocolate. Candidates are from the same food group and used in at least 100 recipes.
