Sponge Drops with Jelly

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.

Prepare the batter

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

  2. Beat the egg whites until stiff.

  3. In a separate bowl, beat the egg yolks until thick.

  4. Gradually add the sugar to the yolks and mix well.

  5. Fold in half of the beaten egg whites and the grated lemon rind.

  6. Gently fold in the flour, then the remaining egg whites, and finally the melted butter.

Bake and serve

  1. Drop spoonfuls of the batter into a buttered pan or small round tins.

  2. Bake for about 10 minutes until lightly golden.

  3. Once cooled, pair the drops with jelly in between, rounded side out.

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

What each ingredient does

Egg whites
Beaten until stiff, they trap air that lifts and gives the drops a light, sponge-like structure.
Egg yolks
Beaten with sugar, they add richness and help set the batter's tender crumb.
Pastry flour
Provides the light starch structure that holds the drops together as they bake.
Sugar
Sweetens the batter and, beaten with the yolks, helps create a thick, stable base.
Melted butter
Adds fat for moisture and a tender texture in the baked drops.

The step that matters

Folding in the egg whites. Folding gently preserves the air beaten into the egg whites. Stirring or deflating the batter makes the drops dense and flat instead of light.

Swap the currant

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

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