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 ↓

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
- Their collagen gives body and a jellied texture as they cook and cool.
- Pigs' ears
- Cartilage and collagen make them chewy and firm after long simmering.
- Vinegar
- Adds acidity that sharpens the flavour and helps preserve the pickled meat.
The step that matters
Fry the feet and ears until golden. The pieces must be dry and the fat hot, otherwise moisture steams the surface instead of browning it and the meat spatters.
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.
“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.
