Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Whiting
Gives the stock a fish base and body as it simmers.
Oysters
Provide the main flavour and tender pieces of shellfish in the soup.
Butter
Enriches the roux and adds richness and a smooth mouthfeel.
Flour
Thickens the stock with the butter as a roux.
Egg yolks
Enrich and thicken the soup when stirred in with cream.
Cream
Adds richness and a smooth, velvety texture to the soup.

The step that matters

Adding the egg yolk and cream mixture. Egg yolks thicken when heated but can scramble if the soup is boiling. Add the mixture off the heat or over very low heat, stirring constantly, so the soup becomes creamy rather than curdled.

Flavor stand-ins for the thyme

How well each one fits the dish's main ingredients (whiting, sauce, oyster, anchovy, carrot, celery, parsley):

  2. Thymethe original
  3. Tarragonabout as good a flavor fit
  4. Marjoramabout as good a flavor fit

Fit is the average pairing score against whiting, sauce, oyster, anchovy, carrot, celery, parsley. 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).
