Why it works: Parsley and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ingredients
Directions
Make the stock
Combine bones, giblets, and trimmings in a large pot.
Add sweet herbs, onions, parsley, carrots, celery, salt, and pepper.
Pour in enough water to cover the ingredients and bring to a boil.
Reduce heat and let it simmer for several hours to extract flavors.
Make the roux and thicken
For thickening, melt 2 ounces of butter in a saucepan over low heat.
Gradually add 2.5 ounces of flour, stirring until smooth and velvety.
Cook the roux slowly until it turns a biscuit brown for brown soups, or keep it white for white soups.
Add the roux to the stock and stir well to combine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bones of cooked meat
- Release gelatin and savory flavor into the water during long simmering.
- Giblets
- Add concentrated meaty flavor to the stock.
- Onions
- Contribute sweetness and aromatic depth as they cook down.
- Carrots
- Add natural sweetness and body to the stock.
- Celery
- Adds aromatic, savory background flavor to the stock.
- Flour (in the method)
- Thickens the stock when cooked with butter into a roux.
The step that matters
Cooking the roux slowly. Flour must be cooked long enough to remove its raw starchy taste and to reach the intended colour. Too much heat browns or scorches the roux unevenly, giving a bitter taste, while too little leaves it pasty and floury.
Swap the onion
How well each one fits the dish's main ingredients (meat, turkey, beef, parsley, carrot, celery, pepper):

Fit is the average pairing score against meat, turkey, beef, parsley, carrot, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
