Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare and simmer
Clean the pork head and feet thoroughly.
Place the head and feet in a large pot with enough water to cover them.
Add chopped onions and spices to the pot.
Simmer for several hours until the meat is tender and falls off the bone.
Make the set
Remove the meat, chop it finely, and strain the broth.
If using gelatin, dissolve it in the hot broth according to package instructions.
Mix the chopped meat with the broth and pour into a mold.
Refrigerate until set, then slice and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork head
- Supplies the meat and connective tissue that become the chopped body of the dish.
- Pork feet
- Release collagen during long simmering, which thickens the broth and helps it set.
- Gelatin
- Adds extra setting power so the chilled broth holds its shape when sliced.
The step that matters
Simmering until the meat is tender. Collagen in the head and feet must break down into gelatin over long, gentle heat. Boiling hard can cloud the broth and toughen the meat, and too short a simmer leaves the broth too weak to set.
Swap the onion
How well each one fits the dish's main ingredients (pork, pepper, gelatin):
- Capsicumfits better
- Potatofits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against pork, pepper, gelatin. Candidates are from the same food group and used in at least 100 recipes.
