Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Rice and Mushroom Croquettes
Ingredients
Directions
Prepare the mushroom stock
Chop the drained mushrooms.
Cook them in the stock or water with onion, carrot, and celery for 15 minutes.
Strain and let cool.
Cook the rice

Shape and chill
Mix in the chopped mushrooms, butter, egg yolk, pepper, and salt.
Let the mixture cool and stiffen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main savory flavor and moisture for the filling.
- Raw rice
- Softens and thickens as it cooks, giving the filling body and helping it hold together.
- Egg yolk
- Binds the filling and adds richness so the croquettes hold their shape.
- Butter
- Adds fat for richness and flavor, and firms as it cools to help shaping.
The step that matters
Let the mixture cool and stiffen before shaping. Cooked rice starch and butter firm as they cool. A warm mixture stays soft and sticky, so the croquettes may lose their shape or split in the oil. Chilling them again before frying helps them keep their form.
Swap the onion
How well each one fits the dish's main ingredients (mushroom, carrot, celery, rice, butter, egg, pepper):
- Capsicumfits better
- Spinachfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against mushroom, carrot, celery, rice, butter, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
