Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Rice Croquettes, Savoury
Ingredients
Directions
Cook the rice and onion
Boil the rice in stock or water until tender and absorbed.
Chop the onion finely and fry it in butter until tender, without browning.
Add herbs and parsley to the frying pan and cook for 2–3 minutes.
Combine the onion mixture with the rice.
Shape and coat
Let the mixture dry in the oven until it is rollable.
Separate the yolk from one egg.
Beat the whole egg with the egg white.
Mix the rice mixture with the beaten eggs thoroughly.
Roll the mixture into balls the size of small walnuts.
Season the balls with pepper and salt.
Coat the balls in flour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Its starch swells and sets as it cooks and dries, giving the croquettes their body.
- Onion
- Softened in butter, it adds sweetness and a savoury base to the mixture.
- Butter
- Fat that carries the onion's flavour and keeps the mixture moist and tender.
- Eggs
- Bind the rice together and set on heating, so the balls hold their shape.
- Mixed savoury herbs
- Add aroma that runs through the rice mixture.
The step that matters
Drying the mixture until it is rollable. Excess moisture keeps the mixture soft and makes the balls fall apart, while over-drying leaves it crumbly. The starch from the rice needs to be firm enough to hold its shape and bind with the egg when it is formed and cooked.
Swap the onion
How well each one fits the dish's main ingredients (rice, butter, parsley, egg, pepper, flour):
