Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Pickled Pigs Feet
Ingredients
Directions
Prepare the feet
Singe the pig feet well.
Pour boiling water over them with baking soda dissolved in it and let stand until cool.
Scrape the feet well with a sharp knife.
Cook and pickle
Rinse and cook in boiling salted water until very tender, leaving at least 1 quart of broth.
Drain off the broth and let it cool.
Remove the fat from the top and reheat the broth.
Add enough strong vinegar to make it tart, along with red peppers, celery seed, and mustard.
Pour the mixture over the feet and let stand until well seasoned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pigs feet
- Main protein; cooking until very tender turns its connective tissue soft and gelatinous.
- Strong vinegar
- Adds the tartness that defines the pickle and helps preserve the feet.
- Baking soda
- Dissolved in boiling water to help loosen the skin and hair before scraping.
- Red peppers
- Contribute heat and aroma to the pickling liquid.
- Celery seed
- Adds a warm, savory aroma to the pickling liquid.
The step that matters
Cooking until very tender. Pig feet are rich in collagen, which must cook long enough to break down into gelatin; undercooked feet stay tough and chewy. Leaving the broth at a simmer in salted water keeps the meat moist as it softens.
Swap the celery
How well each one fits the dish's main ingredients (vinegar, pepper, mustard):
- Tarragonfits better
- Dillfits better
- Capersfits about as well
- Celerythe original
Fit is the average pairing score against vinegar, pepper, mustard. Candidates are from the same food group and used in at least 100 recipes.
