Why it works: Parsley and walnut match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 865 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
To Boil Fresh Fish
Ingredients
Directions
Prepare
Clean the fish thoroughly and rub it with coarse sea salt.
Wrap the fish in a towel and place it in a pot of boiling water.
Cook and serve
Boil the fish rapidly; large fish take 30 to 45 minutes, small fish take 15 to 20 minutes.
Once cooked, transfer the fish to a serving dish.
Cover the fish with egg sauce or drawn butter and garnish with parsley.
Serve with pickled mushrooms, walnuts, and mushroom ketchup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh fish
- Forms the main body of the dish, cooked gently by boiling in its towel.
- Egg sauce or drawn butter
- Adds richness and moisture to the mild, cooked fish.
- Pickled mushrooms
- Adds acidity that cuts through the richness of the fish and sauce.
- Mushroom ketchup
- Adds deep savoury, umami flavour to the plain boiled fish.
The step that matters
Boil the fish rapidly. Rapid boiling brings the water back up to temperature quickly so the fish cooks evenly and stays moist. Cooking times depend on the size of the fish, so check it is cooked through before serving.
Swap the walnut
How well each one fits the dish's main ingredients (fish, egg, parsley, mushroom, ketchup):
- Walnutthe original
- Peasfits about as well
- Beansfits less well
- Chestnutfits less well
Fit is the average pairing score against fish, egg, parsley, mushroom, ketchup. Candidates are from the same food group and used in at least 100 recipes.
