Why it works: Cheese and butter 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 ↓
Rice Au Gratin
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Cook the rice
Wash the rice and add it to a large saucepan of rapidly boiling salted water.
Boil for 12 to 14 minutes, then drain, wash, and dry thoroughly.
Prepare the white sauce as directed.
Assemble and bake
Once the rice is cooked and dry, mix it with the white sauce and season with salt and pepper.
Transfer the mixture to a shallow baking dish or several small molds.
Sprinkle the top generously with grated cheese and add small pieces of butter.
Bake in a 400°F (200°C) oven until nicely browned and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the bulk of the dish, giving it a substantial, starchy body once cooked and dried.
- White sauce
- Binds the rice together and adds creamy moisture so the dish does not dry out in the oven.
- Grated cheese
- Melts and browns on top, adding savoury flavour and a golden crust.
- Butter
- Adds richness and fat that helps the top brown and gives a silky mouthfeel.
The step that matters
Drying the rice thoroughly after boiling. Excess surface water dilutes the white sauce and makes the mixture loose and soggy, so the rice should be fully drained and dried before mixing.
