Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Codfish and Potato Stew
Ingredients
Directions
Prepare the fish
Soak, boil, and flake the codfish into small pieces.
Mix in an equal quantity of mashed potatoes.
Cook the stew
Add 1 tablespoon of butter and 1 tablespoon of milk to make the mixture soft.
Transfer the mixture to a skillet and add a little boiling water to prevent burning.
Turn and toss until the stew is hot but not dry.
Season with pepper and parsley to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Provides the main protein and flaky texture of the stew.
- Mashed potatoes
- Binds the flaked fish and adds body and softness to the mixture.
- Butter
- Adds richness and fat, helping keep the mixture soft and flavourful.
- Milk
- Adds moisture and softness to the mixture.
The step that matters
Turn and toss until hot but not dry. Once the mixture is heated through, further cooking evaporates the moisture from the potatoes and milk, leaving the stew dry and crumbly. Adding a little boiling water earlier helps prevent scorching in the skillet.
Swap the parsley
How well each one fits the dish's main ingredients (potato, butter, milk, pepper):
- Parsleythe original
- Thymefits about as well
- Cinnamonfits less well
- Nutmegfits less well
Fit is the average pairing score against potato, butter, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
