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 meat
In a kettle, combine the meat and onions with cold water.
Set over high heat and stir frequently until browned. If it risks burning, add a spoonful of water as needed.
Stew
Once browned, add the tomatoes, salt, pepper, cayenne, and hot water.
Reduce heat and let it stew slowly for at least two hours. If the stew becomes too dry, add a little water.
Half an hour before serving, stir in the 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 fat, which render and add savory richness to the stew.
- Onions
- Soften and sweeten as they cook, building flavor into the base of the stew.
- Tomatoes
- Add acidity and moisture, rounding out the flavor of the stew.
- Uncooked rice
- Absorbs liquid and thickens the stew as it cooks in the pot.
The step that matters
Browning the meat and onions. Stirring over high heat until browned develops deep flavor through the Maillard reaction. Stirring often and adding water as needed keeps the pot from scorching before the stew begins.
