Directions
Prepare
Fill a large pot with 6 quarts of water and place it by the fire.
Add all saved scraps: bones, bread crusts, bacon, vegetables, and rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bones of cold meat
- Release gelatin and savory flavor into the water as they simmer.
- Fresh bones (purchased)
- Add extra body and richness to the stock.
- Vinegar
- Adds acidity that helps draw minerals and flavor out of the bones.
- Onion
- Contributes sweet, aromatic depth to the broth.
The step that matters
Simmer gently for several hours. A hard boil makes stock cloudy and greasy, while a slow simmer lets collagen from the bones dissolve gradually into a clear, well-flavored liquid.
Swap the onion
How well each one fits the dish's main ingredients (meat, bread, rice, turnip, carrot, parsnip, sugar):
- Leekfits better
- Beetrootfits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against meat, bread, rice, turnip, carrot, parsnip, sugar. Candidates are from the same food group and used in at least 100 recipes.
