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 ↓
Rice Cake
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Whisk the eggs for 30 minutes.
Add rice flour, powdered sugar, and lemon peel to the eggs.
Mix in the fresh butter, previously beaten to a cream.
Bake
Pour the mixture into a buttered tin.
Bake the cake in a 350°F (175°C) oven.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Whisked for a long time, they trap air that gives the cake its light structure.
- Rice flour
- Provides the main starch that sets during baking and forms the cake's body.
- Powdered sugar
- Sweetens the cake and dissolves easily into the batter for a fine crumb.
- Fresh butter
- Adds richness and fat, giving a tender texture and moist crumb.
The step that matters
Whisk the eggs for 30 minutes. Long whisking incorporates air into the eggs, which is the main leavening in a cake with no baking powder. Under-whisking leaves a dense, heavy cake, so the eggs need to be whisked thoroughly before adding the other ingredients.

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