Why it works: Butter and cheese are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Irish Rice
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.
Cook the rice
Melt the butter in a saucepan over medium heat.
Add the chopped onion and cook without browning, stirring constantly.
Add the washed rice and pour in the stock or hot water.
Cook until all the liquid is absorbed and the rice is tender.
Stir in the salt, cayenne pepper, and grated cheese.
Bake and serve
Transfer to a baking dish and sprinkle with additional cheese.
Beat the egg with a tablespoon of grated cheese.
Pour the beaten egg mixture over the rice.
Bake in a 350°F (175°C) oven until slightly browned.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Absorbs the stock as it cooks, becoming tender and forming the body of the dish.
- Butter
- Adds fat and richness, carrying flavor through the onion and rice.
- Cheese
- Melts into the rice and browns on top, adding savory flavor and color.
- Egg
- Binds the rice and sets during baking, giving a firmer, custard-like texture.
- Onion
- Adds savory aroma and sweetness when cooked gently without browning.
The step that matters
Cook the onion without browning. Stirring constantly over medium heat softens the onion and releases its sweetness while keeping it pale. Browning would make the dish taste bitter and change its mild flavor.
Swap the onion
How well each one fits the dish's main ingredients (butter, rice, pepper, cheese, egg):

- Potatofits better
- Onionthe original
Fit is the average pairing score against butter, rice, pepper, cheese, egg. Candidates are from the same food group and used in at least 100 recipes.
