Why it works: Pepper and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 27,814 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Pigs' Foot Jelly
Ingredients
Directions
Prepare the feet
Thoroughly singe, scrape, and wash the pig's feet.
Place the feet in a kettle and boil until the meat separates from the bones.
Make the jelly
Remove the meat and bones from the kettle, leaving the liquid.

Return the chopped meat to the liquid, season with pepper, salt, and vinegar if desired.
Pour the mixture into molds and refrigerate overnight.
Remove the fat that rises to the top before serving.

What each ingredient does
- Pig's feet
- Provide meat, skin and connective tissue that release gelatin into the cooking liquid, which sets the jelly.
The step that matters
Pour the mixture into molds and refrigerate overnight. The jelly sets only when the gelatin released from the bones and connective tissue cools and firms. It needs enough time to chill fully, so pouring into molds too early or skipping the overnight chill can leave it loose.
