Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Roast Chickens
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Tie a slice of bacon on each side of the chicken breast.
Place a bit of butter and half an onion inside each chicken.
Roast and serve
Baste the chickens with butter while roasting.
Serve with watercress and bread sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon
- Adds fat and savoury flavour that keeps the breast meat moist as it roasts.
- Butter
- Adds fat that carries flavour and helps the skin brown and stay moist.
- Onion
- Sits inside the cavity, adding aroma and a mild sweetness to the roasting juices.
The step that matters
Basting the chickens with butter while roasting. Butter spooned over the skin keeps it from drying out and helps it brown evenly. Basting too little leaves pale, dry skin, while the chicken must still reach a safe internal temperature.
Swap the onion
How well each one fits the dish's main ingredients (chicken, butter, watercress, bread, sauce):

- Onionthe original
Fit is the average pairing score against chicken, butter, watercress, bread, sauce. Candidates are from the same food group and used in at least 100 recipes.
