Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Perch, Stewed
Ingredients
Directions
Prepare the fish
Wash, scale, and empty the perch, removing the gills.
Place the perch in a stewpan and cover with weak stock or water.
Add the sliced onion, cloves, parsley, thyme, bay leaf, salt, and pepper.
Simmer gently for 15-20 minutes until the fish is cooked.
Press the flesh to check doneness; it should give way to the touch.
Remove the perch and drain them.
Make the sauce
Strain the cooking liquid, then thicken it with flour and butter.
Boil the sauce quickly for a few minutes.
Stir in the claret, mushroom ketchup, essence of anchovy, cayenne, and chopped parsley.
Serve
Skin the fish, keeping the fins, and place them on a hot dish.
Strain the sauce over the fish and arrange the fins on each side.
Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Perch
- The main fish; it is cooked gently in the stock until the flesh becomes tender and flakes.
- Flour
- Thickens the strained cooking liquid into a smooth, lightly bodied sauce.
- Butter
- Enriches the sauce and carries flavour, adding richness and a smooth mouthfeel.
- Claret
- Adds acidity and wine flavour to the finished sauce.
- Essence of anchovy
- Adds savoury depth and a salty, umami background to the sauce.
The step that matters
Simmer gently for 15-20 minutes until the fish is cooked. Boiling vigorously can break the delicate flesh apart and toughen it. A gentle simmer cooks the fish through while keeping it intact and moist, so checking doneness by pressing the flesh matters.
Swap the onion
How well each one fits the dish's main ingredients (clove, parsley, thyme, pepper, flour, butter, mushroom):
- Shallotfits better
- Carrotfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against clove, parsley, thyme, pepper, flour, butter, mushroom. Candidates are from the same food group and used in at least 100 recipes.
