Why it works: Milk and butter 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 ↓
Rice Cheese
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the rice
Boil the rice in water until tender.
Make the cheese sauce
Melt the butter in a saucepan, add the flour, and mix well.
Stir in the milk and cook until the sauce boils.
Add the cooked rice and season with salt, cayenne, and black pepper.
Stir in 3 oz of cheese and pour the mixture into a buttered pie dish.
Bake and serve
Sprinkle the remaining cheese on top and bake in a hot oven at 400°F (200°C) until browned.

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 casserole, giving it body and a soft, tender texture.
- Flour
- Thickens the melted butter and milk into a smooth sauce that holds the rice together.
- Cheese
- Adds richness and flavour, and melts into the sauce while browning on top.
- Butter
- Provides fat for the roux and adds richness to the sauce.
- Milk
- Forms the liquid of the sauce, which thickens as the flour cooks and swells.
The step that matters
Cooking the sauce until it boils. Flour must be cooked in the butter and milk until the sauce boils so the starch swells and thickens fully. Undercooked sauce stays thin and tastes of raw flour.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (milk, rice, cheese, butter, flour, pepper):
- Potatofits better
- Capsicumfits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against milk, rice, cheese, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
