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
Preheat the oven to 350°F (175°C).
Mix the dough
In a large bowl, combine flour, ground rice, sugar, and butter.
In a separate bowl, mix the dissolved ammonia with cold water. Add the ammonia mixture to the dry ingredients and mix well.
Incorporate the eggs and lemon flavoring into the mixture.
Bake and finish
Wash the top with beaten egg and dust with broken sugar.
Bake in the preheated oven until golden brown.

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
- Ammonia
- Releases gas in the dough during baking, helping it rise and become light and open.
- Eggs
- Add structure and richness, setting as the dough bakes and giving it a tender crumb.
- Butter
- Adds fat that tenderises the crumb and carries flavour through the dough.
- All-purpose flour
- Provides the main structure of the dough as its proteins and starches set in the oven.
- Sugar
- Sweetens the cake and helps the top brown during baking.
The step that matters
Mixing the dissolved ammonia into the dry ingredients. Ammonia breaks down into gas as the dough heats, so it must be evenly dispersed in the mix and the dough baked promptly to get an even, light rise instead of uneven holes or a dense result.
Swap the lemon
How well each one fits the dish's main ingredients (flour, rice, sugar, butter, egg):

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