Why it works: Rice and lemon are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,366 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓

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.
Prepare
Separate the yolks and whites of the eggs.
Mix the yolks with the rice flour.
Add the sugar and lemon essence to the yolk mixture.
Bake
Fold in the beaten egg whites.
Pour the mixture into a tin.
Bake at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped by folding add lift, and yolks add richness and structure.
- Rice flour
- Provides the cake's base structure without gluten.
- Loaf sugar
- Adds sweetness and helps the cake brown in the oven.
The step that matters
Fold in the beaten egg whites. Folding gently keeps the air beaten into the whites. Stirring or deflating them makes the cake dense instead of light.
Swap the lemon
How well each one fits the dish's main ingredients (egg, rice, flour, sugar):
- Raisinfits better
- Vanillafits better
- Coconutfits about as well
- Lemonthe original
Fit is the average pairing score against egg, rice, flour, 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.
