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 Sandwich
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. 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.
Prepare
Preheat the oven to 350°F (175°C).
In a bowl, mix the sugar and flour together.
In a separate bowl, beat the eggs until frothy.
Make the batter
Combine the egg mixture with the sugar and flour, then add a pinch of baking soda.
Pour the batter into a greased baking pan and spread evenly.
Bake and serve
Bake for about 15-20 minutes or until golden brown.
Let it cool.
Roll it up and slice to serve.

Flour and egg 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
- Beaten until frothy, they trap air that gives the cake its light, airy structure.
- Flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Sugar
- Adds sweetness and helps keep the crumb tender and moist.
- Baking soda
- Releases gas in the batter to help the cake rise.
The step that matters
Bake until golden, not longer. Overbaking drives off moisture and dries the sponge, so it becomes brittle and cracks when rolled. Check for golden color at the shortest time.
“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.
