Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Starch that absorbs the milk and tomato liquid, giving the dish its creamy, soft body.
- Milk
- Liquid that cooks the rice and gives a creamy, rich texture as it reduces.
- Tomatoes
- Provide moisture, acidity and a fresh tomato flavour that carries through the dish.
- Onions
- Add savoury sweetness and aromatic depth as they soften during boiling.
- Grated cheese
- Melts into the hot rice at the end, adding richness and savoury flavour.
The step that matters
Boil until soft, adding milk as needed. Rice absorbs liquid as it cooks, so it can scorch or stay firm if the pan dries out. Stirring and topping up with milk keeps the texture creamy and evenly cooked.
Swap the onion
How well each one fits the dish's main ingredients (milk, rice, tomato, pepper, cheese):

Fit is the average pairing score against milk, rice, tomato, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
