Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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.
Prepare
Cook the rice in 2 cups of water until tender, then let it cool.
Assemble and bake
In a baking dish, layer the rice and grated cheese, seasoning each layer with pepper, salt, and butter.
Pour milk over the layers to cover them.
Bake in a 350°F (175°C) oven for 20 to 30 minutes.

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 bake and soaks up milk and butter for a soft, moist texture.
- Grated cheese
- Melts into the rice, adding richness and a savoury, binding flavour.
- Milk
- Covers the layers and moistens them as the bake cooks, keeping the rice tender.
- Butter
- Adds fat that enriches the flavour and helps the layers stay moist.
The step that matters
Let the rice cool before layering. Cooling the cooked rice keeps it from turning mushy and helps it hold its shape in the layers, so the bake sets evenly rather than becoming gluey.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
