Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Separate the eggs.
Beat the yolks until creamy.
Add the powdered sugar and beat together.
Beat the egg whites until very stiff and dry.
Fold the egg whites into the yolk mixture.
Sift in the pastry flour. Stir quickly.
Line a large shallow pan with parchment paper.
Pour the batter into the pan.
Bake and roll
Bake at 400°F (200°C) for 20 minutes.
While warm, cut off the edges.
Spread with jelly.
Roll up.
Wrap in a towel.
Place in a cool place.
Cut with a sharp knife before serving.

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
- Whipped whites trap air and give the sponge its light, rollable structure.
- Powdered sugar
- Sweetens the batter and helps the yolks form a smooth, creamy base.
- Pastry flour
- Provides the light starch structure that holds the sponge together when rolled.
- Jelly
- Adds sweetness and moisture to the filling and keeps the rolled sponge from drying out.
The step that matters
Fold the egg whites into the yolk mixture. Whites deflate easily when overmixed or stirred roughly. Gentle folding keeps the air bubbles that make the sponge rise and stay tender, so it can be rolled without cracking.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
