Why it works: Sage and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,445 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Pork Jelly
Ingredients
Directions
Prepare
Salt the pig's feet and ears for 2-3 days.
Make the stock
Place them in a saucepan and cover with water.
Boil quickly for several hours until the meat separates from the bone.
Remove the meat, discard the bones, and cut the meat into very small pieces.
Return the meat to the saucepan and add black pepper.
Boil slowly until it thickens and becomes almost jelly-like.
Set and serve
Pour into a mold and refrigerate until cold.
If desired, add chopped herbs just before pouring to avoid discoloration.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig's feet
- Their collagen-rich connective tissue breaks down into gelatin, which sets the liquid into a jelly.
- Pig's ears
- Their cartilage and skin add gelatin, helping the stock thicken and set firmly when cold.
The step that matters
Boil slowly until it thickens. Gentle simmering concentrates the gelatin-rich liquid without toughening the meat or clouding it. Boiling hard can make the jelly cloudy and fail to set evenly.
Swap the mace
The recipe marks mace as optional. How well each one fits the dish's main ingredients (pepper, sage, parsley):
- Marjoramfits better
- Thymefits better
- Rosemaryfits better
- Macethe original
Fit is the average pairing score against pepper, sage, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
