Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Rice Croquettes
Ingredients
Directions
Make the rice mixture
Boil rice in chicken broth mixed with boiling water and salt until soft.
Drain the rice and stir in beaten eggs, butter, flour, pepper, and lemon peel.
Heat the mixture in a saucepan until thick and hot, then spread it out to cool.
Shape and fry
Once cool, flour your hands and shape the mixture into long balls.
Roll each ball in raw egg, then coat with cracker crumbs.
Fry the croquettes in hot oil until golden brown.

Butter and flour 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
- Rice
- Cooks into a soft, starchy base that holds the croquettes together.
- Eggs
- Bind the mixture and set when heated, giving structure to the croquettes.
- Chicken broth
- Adds savory flavor as the rice absorbs it while cooking.
- Butter
- Adds richness and fat, contributing to a tender interior.
- Flour
- Thickens the mixture and helps the balls hold their shape.
The step that matters
Cooling before shaping. The mixture must be cool and thick enough to handle. Shaping it warm makes it sticky and prone to falling apart, while thorough cooling helps the balls keep their form in hot oil.
Swap the lemon
How well each one fits the dish's main ingredients (rice, chicken, egg, butter, flour, pepper):
- Lemonthe original
- Coconutfits about as well
- Avocadofits less well
- Mangofits less well
Fit is the average pairing score against rice, chicken, egg, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
