Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Stewed Fish
Ingredients
Directions
Prepare
Sprinkle the fish with salt.
Boil 1 pint of water with the sliced onion until cooked, then pour off the water.
Cook the fish
Add 1 cup of water, lemon juice, ¼ teaspoon salt, pepper, and herbs to the pot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, turning firm and flaky as its proteins set when cooked.
- Onion
- Adds sweetness and aroma to the cooking water as it softens.
- Lemon juice
- Adds acidity that brightens the flavor of the fish and gravy.
- Flour
- Its starch swells in the hot liquid, thickening the gravy.
- Butter
- Adds fat for richness and a smoother mouthfeel to the gravy.
The step that matters
Boil the fish until done. Fish cooks quickly, and prolonged vigorous boiling can make it tough and break it apart. Watch it closely and stop once it turns opaque and flakes easily.
Swap the onion
How well each one fits the dish's main ingredients (fish, lemon, pepper, parsley, butter, flour):
- Shallotfits better
- Carrotfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against fish, lemon, pepper, parsley, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
