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 ↓
To Make Rice Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Beat the egg whites and yolks separately until well combined.
Add the lemon zest, sugar, and ground rice; mix thoroughly.
Bake
Pour the mixture into a tin and bake in a 400°F (200°C) oven for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air and set the cake, while yolks add richness and moisture.
- Sugar
- Adds sweetness and helps the cake brown as it bakes.
- Ground rice
- Provides the main structure and a tender, slightly dense crumb.
- Lemon zest
- Adds aroma and a bright citrus flavour.
The step that matters
Beating the egg whites separately. Whites must be beaten until they hold air, since that trapped air lifts the batter as it bakes. Under-beaten whites leave a dense cake, and deflating them during mixing undoes the lift.

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