Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Prepare

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pigs' feet
- Provide gelatinous connective tissue that gives a tender, rich texture after boiling.
- Pigs' ears
- Provide gelatinous cartilage that turns tender when boiled and then firms up when pickled.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the pickled meat.
- Flour
- Helps form a dry coating that lets the pieces brown when fried.
The step that matters
Dry the feet and ears before frying. Surface moisture prevents browning and causes spattering in hot fat, so the pieces must be patted dry before they go into the pan.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, butter, flour):
- Shallotfits better
- Mustardthe original
- Chivefits about as well
- Cucumberfits about as well
Fit is the average pairing score against vinegar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
