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

What each ingredient does

Oysters
Are the main ingredient, cooking until their edges curl to show they are done.
Egg yolk
Thickens the mixture as it cooks and gives it a richer, creamier texture.
Flour
Lightly thickens the buttery mushroom mixture so it holds together around the oysters.
Mushrooms
Provide the earthy base of the duxelles that the oysters are cooked in.

The step that matters

Cook until the mixture thickens. Egg yolk thickens when heated but can scramble and turn grainy if the heat is too high or it cooks too long. Cook gently and stir constantly so it becomes smooth and creamy.

  2. Shallotbetter flavor fit
  3. Capsicumbetter flavor fit
  4. Onionthe original

Fit is the average pairing score against butter, mushroom, flour, oyster, pepper, lemon, egg. 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).
