Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh beef
- Forms the main body of the dish, becoming tender as it cooks slowly.
- Fat ham or bacon
- Adds fat that melts into the meat, keeping it moist and flavorful during cooking.
- Onion
- Adds aroma and savory flavor as it seasons the meat.
The step that matters
Cook by the fire without water. The covered pan traps the meat's own moisture, so it must be watched closely to prevent burning while the collagen slowly breaks down into tender meat and gravy.

Fit is the average pairing score against beef, ham, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
