Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Thickens the sauce as it softens and is rubbed through, giving body and a smooth texture.
- Milk
- Cooks the rice to tenderness and adds moisture and richness to the sauce.
- Cream, milk, or melted butter
- Enriches the final sauce with fat for a silkier mouthfeel and mellow flavour.
The step that matters
Rubbing the rice through a colander. The rice must be cooked fully tender before it is pressed, so it breaks down into a smooth purée rather than a grainy texture. Under-cooked grains will not pass cleanly and leave the sauce gritty.
Swap the onion
How well each one fits the dish's main ingredients (rice, cream):
- Potatofits better
