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 ↓
Rolled Jelly Cake
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.
Prepare the batter
Preheat the oven to 400°F (200°C).
Beat the egg yolks until light.
Add the sugar and mix well.
Stir in the water and salt.
Gradually add the flour mixed with baking powder.
Pour the batter into well-greased long, shallow biscuit tins.
Bake and roll
Bake until golden.
Turn the cake out onto a damp towel on a breadboard.
Spread jelly over the top and roll up while warm.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 in the batter and form the light, sponge-like structure of the cake.
- Sugar
- Sweetens the cake and helps keep the crumb tender and moist.
- Flour
- Sets during baking to give the cake its body and sturdiness for rolling.
- Baking powder
- Releases gas when heated, helping the cake rise and stay airy.
The step that matters
Roll the cake while warm. A freshly baked sponge is flexible when warm. As it cools, the crumb stiffens and is likely to crack when rolled, so rolling it right away keeps the roll intact.
“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.
