Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork chine
- Provides the main meat, which salting firms and seasons before roasting.
- Onions
- Caramelise when fried golden, adding sweetness and colour to the gravy.
- Vinegar
- Adds acidity that brightens the rich, fatty gravy.
- Mushrooms
- Add savoury depth and moisture to the gravy.
The step that matters
Frying the onions until golden. Onions cooked too quickly or too little can turn bitter or stay pale and raw-tasting. Frying gently until golden develops sweetness and colour through browning, which gives the gravy its flavour base.
