Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fat livers
- Provide the main body and rich flavor of the sauce once pounded smooth.
- Butter
- Adds richness and a smooth, silky texture when worked into the livers.
- Port wine
- Adds sweetness and depth, and its liquid helps the sauce cook down.
- Cullis
- Supplies liquid and savory body so the mixture can stew together.
The step that matters
Stew all ingredients together for 5 minutes. Stewing for only the stated time gently cooks the livers through without toughening them. Overcooking causes proteins to tighten and turn grainy and dry, so the sauce can lose its smooth texture.
Swap the coriander
How well each one fits the dish's main ingredients (liver, butter, parsley, tarragon, onion, port wine, pepper):
- Thymefits better
- Marjoramfits better
- Sagefits better
- Corianderthe original
Fit is the average pairing score against liver, butter, parsley, tarragon, onion, port wine, pepper. Candidates are from the same food group and used in at least 100 recipes.
