Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk or cream
- Forms the base of the sauce, giving it a smooth, rich body.
- Flour
- Thickens the liquid into a sauce as it cooks with the milk or cream.
- Butter
- Adds fat and richness to the sauce and carries flavour.
- Halibut or other fish
- Forms the main body of the dish, giving it its flaky texture and flavour.
The step that matters
Add milk or cream, butter, and flour to the boiling onions.. Flour must be fully mixed in and the liquid kept at a boil so it cooks through and thickens evenly; adding it to a simmer or unstirred can leave lumps and a raw floury taste.
Flavor stand-ins for the mace
How well each one fits the dish's main ingredients (onion, parsley, milk, butter, flour, fish):
- Capersbetter flavor fit
- Thymebetter flavor fit
- Nutmegbetter flavor fit
- Macethe original
Fit is the average pairing score against onion, parsley, milk, butter, flour, fish. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
