Why it works: Whiting and sauce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 236 recipes mention both. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Oyster Soup
Ingredients
Directions
Prepare the oysters and stock
Put the oysters into a small saucepan with their liquid and bring to a boil.
Remove the gills and gristle, cut the oysters into quarters, and set aside.
Cut the whiting and add it to the stock along with the oyster gills, anchovy, carrot, celery, thyme, mace, and peppercorns in a saucepan.
Simmer gently for one hour, then strain the mixture.
Make the soup
Melt the butter in a saucepan, stir in the flour until smooth, then add the strained fish stock and stir until it boils.
Cook for three minutes.
Beat the egg yolks and mix in the cream, then add to the soup.
Season with lemon juice, cayenne, and coarse sea salt to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whiting
- Gives the stock its fish flavour and body as it simmers.
- Oysters
- Provide the main shellfish flavour and tender texture in the finished soup.
- Butter
- Enriches the soup and carries flavour, and with flour forms the base for thickening.
- Flour
- Thickens the soup by forming a roux with the butter.
- Egg yolks
- Enrich and thicken the soup, giving it a smoother, richer texture.
- Cream
- Adds richness and a silky mouthfeel to the finished soup.
The step that matters
Adding the egg yolks and cream. Egg yolks thicken when heated, but if the soup is too hot when they are added they can scramble and turn grainy. Keep the soup below a boil while stirring them in.
Flavor stand-ins for the thyme
How well each one fits the dish's main ingredients (whiting, sauce, oyster, anchovy, carrot, celery, parsley):
- Capersbetter flavor fit

- Tarragonabout as good a flavor fit
- 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).
