Pigs’ Foot Jelly

Ingredients

Directions

Prepare the feet

  1. Soak pigs' feet in a pickle for a few days.

  2. Cook the feet in enough water to cover them until the meat easily separates from the bones.

Set the jelly

  1. Combine the cooking water with the meat and vinegar.

  2. Pack the mixture into pails or beef bungs.

  3. Chill thoroughly in cold water.

  4. To prevent mold, sprinkle the top with a mixture of ground ginger and white pepper.

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

What each ingredient does

Pigs' feet
Provide meat and collagen that set into a firm jelly as the mixture cools.
Vinegar
Adds acidity that gives the jelly a sharp, tangy flavor.
White pepper
Adds sharp heat and, sprinkled on top, helps deter mold on the surface.
Ginger
Adds aromatic warmth and, sprinkled on top, helps deter mold on the surface.

The step that matters

Cooking the feet until the meat easily separates from the bones. Cooking long enough breaks down collagen in the connective tissue into gelatin, which is what lets the liquid set into jelly when chilled. Undercooked feet yield less gelatin and a weaker set.

Swap the white pepper

How well each one fits the dish's main ingredients (vinegar, ginger):

  1. Allspicefits better
  2. Clovefits better
  3. Turmericfits better
  4. White pepperthe original

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