Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- The main cut; its long marinade and roasting turn it tender and flavourful.
- Bacon
- Larding adds fat and salty, smoky flavour that melts into the lean meat as it roasts.
- Vinegar
- Its acidity tenderises the surface of the beef during the long marinade and adds tang.
- Onion
- Sliced into the marinade, it adds aromatic sweetness and flavour to the pickle.
The step that matters
Let it marinate in the pickle for 12 hours. Vinegar is acidic and only penetrates and softens the surface of meat slowly. Too short a marinade leaves the beef tough and sharp-tasting on the outside, so the full time matters.
Swap the parsley
How well each one fits the dish's main ingredients (beef, vinegar, onion, sauce):
- Garlicfits better
- Tarragonfits better
- Capersfits better
- Parsleythe original
Fit is the average pairing score against beef, vinegar, onion, sauce. Candidates are from the same food group and used in at least 100 recipes.
