Why it works: Tomato and rice 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 ↓
Persian Stew
Ingredients
Directions
Brown the base
In a kettle, combine the meat and onions with ½ cup of cold water.
Set over high heat and stir frequently until the meat and onions are well browned. If it starts to burn, add a spoonful of water as needed.
Stew
Once browned, add 1 can of tomatoes, salt, pepper, and cayenne.
Pour in 2 quarts of hot water and reduce heat to simmer.
Let it stew slowly for at least 2 hours. If the stew dries out, add a little more water.
Finish with rice
Half an hour before serving, stir in ½ cup of uncooked rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Provides the main protein and rich flavour as it browns and softens during the long stew.
- Onions
- Browning releases sweetness and depth that flavour the broth.
- Tomatoes
- Add acidity and body to the stewing liquid.
- Uncooked rice
- Absorbs liquid and thickens the stew as it cooks.
The step that matters
Browning the meat and onions over high heat. Browning drives Maillard reactions that build deep flavour. If the pan dries and scorches, the flavour turns bitter, so a little water must be added as needed while stirring.
