Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork chops
- Provide the main protein, which browns in hot fat and stays juicy when cooked briefly.
- Lard
- Conducts heat for frying and adds richness and browning to the chops and onions.
- White onions
- Become sweet and golden when fried, adding flavour and contrast to the rich chops.
- Flour
- Coats the onion rings so they brown crisply and hold their shape in the hot fat.
The step that matters
Frying the onions in boiling fat. Flour-coated onions need hot fat to crisp and turn golden quickly. If the fat is not hot enough, they absorb oil and turn soggy instead of crisp.
Swap the white pepper
How well each one fits the dish's main ingredients (pork, onion, flour):

Fit is the average pairing score against pork, onion, flour. Candidates are from the same food group and used in at least 100 recipes.
