Ingredients
Directions
Make the stock
Boil the ham in water to cover it.
Add onions, garlic, shallots, bay leaf, sweet herbs, cloves, and peppercorns.
Keep the pot covered and let it simmer for three hours.
Strain the liquor and keep it for later use.
Reduce and set
When ready, boil the liquor with poultry or meat until reduced to 3 pints.
Let it cool; it will turn into a jelly suitable for ragouts or hashes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham
- Gives the liquid its savoury, meaty flavour and salt as it simmers.
- Onions
- Add sweetness and depth of flavour to the stock as they cook down.
- Shallots
- Contribute a mild, aromatic sweetness to the stock.
- Garlic
- Adds a pungent aroma that mellows during the long simmer.
The step that matters
Reducing the liquor to 3 pints. Boiling concentrates the dissolved gelatin and flavour from the ham and bones; too little reduction leaves the stock thin and unable to set into a jelly on cooling.
Swap the clove
How well each one fits the dish's main ingredients (ham, onion, garlic, shallot):
- Capersfits better
- Thymefits better
- Parsleyfits better
- Clovethe original
Fit is the average pairing score against ham, onion, garlic, shallot. Candidates are from the same food group and used in at least 100 recipes.
