Why it works: Rice and tomato match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,065 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Risotto a Ritalienne {Italian Risotto}
Ingredients
Directions
Prepare
Wash the rice well, then drain and dry it.
Chop the onion finely and fry it in hot butter in a saucepan until light brown.
Add the rice and shake the pan over the heat for a few minutes.
Cook the risotto
Season with salt, pepper, nutmeg, and saffron, then moisten with a little stock.
As the rice swells, gradually add more stock.
When the stock is used up, add the tomato sauce gradually.
Once the rice is tender, mix in the grated cheese and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Italian or patna rice
- Starch that absorbs stock and swells, giving the risotto its creamy, tender body.
- Butter
- Fat that coats the rice grains and adds richness and flavour when the onion is fried.
- Parmesan cheese
- Melts into the hot rice at the end, adding savoury flavour and creaminess.
- Tomato sauce
- Adds moisture, acidity and colour, flavouring the rice as it is absorbed.
- Stock
- Liquid that the rice absorbs gradually, cooking it while building savoury flavour.
- Saffron
- Provides distinctive aroma and a golden colour to the rice.
The step that matters
Adding the stock gradually. Rice releases starch as it is stirred and absorbs liquid slowly. Adding stock in small amounts as it is absorbed keeps the grains moist and creamy. Adding it all at once leaves the rice soggy or unevenly cooked.
Swap the nutmeg
