Ingredients
Directions
Prepare the salmon

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main body of the dish and carries the flavor of the salt and basting fat.
- Butter rolled in flour
- Thickens the sauce as the flour-coated butter melts and mixes into the liquid.
- White wine
- Adds acidity and aroma, and its liquid reduces during boiling to concentrate flavor.
- Mushrooms
- Contribute earthy savory flavor to the sauce as they simmer.
- Shallot
- Adds a mild sweet-savory aroma to the sauce as it cooks.
The step that matters
Boil the sauce for 30 minutes. A long boil concentrates the wine and vegetables, so the sauce can turn too strong or reduce too far if left unattended. Watching the volume keeps the flavor balanced before straining.
Swap the parsley
How well each one fits the dish's main ingredients (salmon, butter, shallot, mushroom, flour, pepper, white wine):

Fit is the average pairing score against salmon, butter, shallot, mushroom, flour, pepper, white wine. Candidates are from the same food group and used in at least 100 recipes.
