Why it works: Carrot and parsley 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 ↓
Fish Broth

Simmer until reduced to 1 quart.
Strain the broth and add the sliced potatoes, carrot, leek, parsley, and bay leaf.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down slightly as they simmer, thickening the broth and giving it body.
- Oysters
- Add briny, savoury flavour and tender texture when cooked gently.
- Leek
- Adds mild, sweet onion-like aroma to the broth.
- Sherry
- Adds acidity and aromatic depth to the broth.
The step that matters
Cook the oysters gently. Oysters turn rubbery and shrink when boiled hard or overcooked. Holding a gentle simmer for about 10 minutes cooks them through while keeping them tender and plump.
Swap the leek

Fit is the average pairing score against fish, potato, carrot, parsley, oyster, sherry, pepper. Candidates are from the same food group and used in at least 100 recipes.
