Prepare the oysters

Peptonize

  2. Heat the mixture to blood temperature (about 98.6°F or 37°C) and maintain it for 30 minutes, stirring occasionally.

  3. Add the milk and keep the temperature for an additional 10 to 20 minutes.

Finish and serve

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

What each ingredient does

Oysters
Provide the main body and flavor of the dish once minced and broken down.
Milk
Adds moisture and creaminess to the mixture as it is held warm.
Extract of pancreas
Enzymes that break down the oyster proteins, making the mixture softer and more digestible.
Bicarbonate of soda
Raises the alkalinity so the pancreatic enzymes work effectively.
Gelatine
Sets the mixture into a firm jelly when chilled, in the optional cold version.

The step that matters

Holding the mixture at blood temperature for 30 minutes. Pancreatic enzymes work best near body temperature. Too cool and breakdown is slow; too hot and the enzymes are destroyed, so the temperature should be held steady and not overshot.

Swap the tomato

The recipe marks tomato as optional. How well each one fits the dish's main ingredients (oyster, milk):

  1. Potatofits better
  2. Cucumberfits better
  3. Asparagusfits about as well
  4. Tomatothe original

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