Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Roll 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.
Make the batter
Preheat the oven to 400°F (200°C).
Beat the eggs and brown sugar together until well combined.
Mix the cream of tartar and baking soda into the milk, then stir in the lemon extract.
Add the milk mixture to the egg and sugar mixture, then fold in the flour.
Spread the batter thinly on a long baking pan.
Bake and roll
Bake until done.
Immediately spread jelly on top and roll the cake up.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness as they set and bind the batter.
- Flour
- Forms the gluten and starch framework that gives the cake its body.
- Cream of tartar
- Acidifies the batter so baking soda reacts and helps the cake rise.
- Baking soda
- Reacts with the acidic cream of tartar to release gas that lightens the cake.
- Brown sugar
- Adds sweetness, moisture and a caramel note while tenderising the crumb.
The step that matters
Immediately spread jelly on top and roll the cake up.. The cake is flexible only while warm; once it cools it stiffens and cracks when rolled. Rolling promptly while the crumb is still pliable prevents breaking and keeps the spiral neat.
