Puree, Oyster-and-Onion

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Drain the oysters and reserve the liquid.

  2. Chop the onion finely and sauté it in butter until soft.

Make the puree

  1. Add the flour and stir for 1 minute.

  2. Pour in the milk and oyster liquid, stirring until thickened.

  3. Add the oysters and cook for 5 minutes.

  4. Season with salt and pepper, then serve hot.

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

What each ingredient does

Oysters
Provide the main flavour and tender texture of the puree.
Onion
Adds sweetness and aroma as it softens in butter.
Butter
Carries the onion's flavour and adds richness.
Milk
Forms the liquid base that the flour thickens into a smooth sauce.
Flour
Thickens the milk and oyster liquid into a smooth, body-rich sauce.

The step that matters

Pour in the milk and oyster liquid, stirring until thickened. Flour must be cooked into the butter first and the liquid added gradually while stirring, otherwise lumps form and the sauce will not thicken smoothly.

Swap the onion

How well each one fits the dish's main ingredients (oyster, butter, milk, pepper, flour):

  1. Potatofits better
  2. Shallotfits better
  3. Capsicumfits better
  4. Onionthe original

Fit is the average pairing score against oyster, butter, milk, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
