Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Passover Jelly Roll
Ingredients
Directions
Make the batter
Beat yolks and sugar together until light.
Add grated rind and cake meal that has been sifted four times.
Add salt to egg whites.
Beat egg whites until stiff.
Fold egg whites into dough.
Line a jelly roll pan with wax paper.
Grease the pan heavily.
Spread dough evenly on the pan.
Bake at 350°F for 12 minutes.
Roll and finish
When done, lift the cake out of the pan with the wax paper.
Place the cake on a damp cloth for a few minutes.
Invert the cake onto waxed paper sprinkled with sugar.
Remove the wax paper from the cake.
Spread jelly (beaten smooth or boiled frosting) over the cake.
Roll the cake up.
Wrap the roll in waxed paper.
Wrap the waxed paper in a damp cloth for about 15 minutes so that the roll holds its shape.
Remove the wrapping.
Dust the roll with powdered sugar.
Nutrition, whole recipe (rough)

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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 for lift, and yolks add richness and structure to the sponge.
- Matzo cake meal
- Provides the flour-like structure that holds the sponge together when baked.
- Sugar
- Sweetens the cake and helps the yolks whip to a light, stable foam.
The step that matters
Fold egg whites into dough. Folding gently keeps the air bubbles in the whipped whites. Stirring or deflating them makes the sponge dense and flat after baking.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
“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.
