Why it works: Lemon and rice 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 ↓
Rice Cake, Without Butter
Ingredients
Directions
The book says “a warm oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Separate the egg whites from the yolks.
Whisk the egg whites until stiff peaks form.
Mix in the yolks, sugar, and lemon raspings.
Whisk over low heat until thick and light, about 30 minutes.
Remove from heat and whisk until cool.
Stir in the all-purpose flour and rice flour.
Bake
Pour the batter into paper-lined cake pans.
Bake in a moderate oven at 350°F (175°C) until done.

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
- Whites trap air for lift, and yolks add richness and structure as the batter sets.
- Sugar
- Sweetens the cake and helps give the batter body and a tender crumb.
- All-purpose flour
- Provides the main structure that holds the cake together as it bakes.
- Rice flour
- Adds a lighter, more delicate texture to the crumb than wheat flour alone.
- Lemon raspings
- Add bright aroma and flavor from the citrus zest.
The step that matters
Whisk over low heat until thick and light. Gentle heat thickens the eggs and sugar slowly, so they reach a thick, airy state without scrambling. Too much heat can curdle the eggs, and too little leaves the batter thin and unable to hold air.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, flour, rice):

- Lemonthe original
Fit is the average pairing score against egg, sugar, flour, rice. Candidates are from the same food group and used in at least 100 recipes.
