Why it works: Chicken and tomato match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 6,027 recipes mention both. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole chicken
- Provides the main protein and meat that cooks through in the sealed bag.
- All-purpose flour
- Thickens the cooking liquid into a light sauce around the chicken.
- Onion
- Adds savory sweetness and aroma as it softens in the bag.
- Water, stock, or wine
- Creates steam and moisture so the chicken stays tender in the sealed bag.
The step that matters
Seal the bag before baking. A tight seal traps steam so the chicken braises in its own juices; a leak lets moisture escape and dries the meat.
Flavor stand-ins for the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (chicken, pepper, flour, ketchup, onion, parsley, thyme):

Fit is the average pairing score against chicken, pepper, flour, ketchup, onion, parsley, thyme. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
