Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Chicken Casserole
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 300°F (150°C).
Place the chicken in a casserole dish.
Add the potatoes, carrots, and onion.
Stir in the peas, bay leaf, mace, salt, and pepper.
Pour in the stock or hot water.
Cook
Cook the chicken for 30 minutes before adding the vegetables.
Cover and cook slowly until the chicken and vegetables are tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the main protein, which becomes tender through long, gentle cooking.
- Potatoes
- Their starch softens and slightly thickens the cooking liquid as they cook.
- Carrots
- Release natural sugars as they cook, adding gentle sweetness.
- Onion
- Adds aroma and savory depth to the cooking liquid as it softens.
- Stock or hot water
- Provides the moisture that cooks the chicken and vegetables gently.
The step that matters
Cover and cook slowly until tender. Low, slow heat under a cover breaks down the connective tissue in the chicken while trapping moisture. Cooking too hot or uncovered can toughen the meat and dry out the liquid.
Swap the mace
How well each one fits the dish's main ingredients (chicken, potato, carrot, onion, peas, pepper):
- Garlicfits better
- Parsleyfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against chicken, potato, carrot, onion, peas, pepper. Candidates are from the same food group and used in at least 100 recipes.
