Why it works: White pepper and ginger work together. They rank in the top 16% of all ingredient pairs, and cooks put them together in 388 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Making Pigs’ Foot Jelly
Ingredients
Directions
Prepare the feet
Soak the pigs' feet in a strong pickle for a few days.
Cook the feet in a kettle with enough water to cover them until the meat easily comes off the bones.
Pack and chill
Combine the cooked meat with vinegar and pack into paraffined pails or beef bungs.
To prevent mold, sprinkle a mixture of fine ground ginger and white pepper on top before sealing.
Chill the packages in cold water until thoroughly chilled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pigs' feet
- Provide the collagen-rich meat and connective tissue that set the jelly as it chills.
- Vinegar
- Adds acidity that sharpens flavour and helps preserve the packed meat.
- White pepper
- Adds sharp aroma and flavour; sprinkled on top to help deter mold.
- Ginger
- Adds aromatic warmth to the flavour; sprinkled on top with the pepper.
The step that matters
Chill the packages thoroughly. Gelatin from the collagen in the feet only sets fully when the liquid is well cooled, so the jelly firms properly and holds its shape when sliced.
Swap the white pepper
How well each one fits the dish's main ingredients (meat, vinegar, ginger):
- Turmericfits better
