Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- The main meat, which becomes firmer and more tender as it cooks slowly.
- Salt pork
- Adds fat and savory flavor as it renders into the liver and onions.
- Onions
- Release sweetness and moisture as they soften during cooking.
- Vinegar
- Adds acidity that brightens the rich flavor of the liver.
- Salad oil
- Adds fat that helps keep the liver moist during cooking.
- Claret
- Adds acidity and wine aroma to the cooking liquid.
The step that matters
Cook the liver over low heat. Liver is lean and dense, and high heat or long cooking tightens its proteins, making it dry and tough. Gentle, low heat keeps it tender and moist.
Swap the onion
How well each one fits the dish's main ingredients (liver, pepper, pork, vinegar):
- Capsicumfits better
- Mustardfits better
- Onionthe original
- Tomatofits about as well
Fit is the average pairing score against liver, pepper, pork, vinegar. Candidates are from the same food group and used in at least 100 recipes.
