Ham / Smoked Stock
Fond de jambon fumé · A savory, deeply flavored liquid foundation produced by simmering smoked ham bones—often with ham hocks, feet, or knuckles—in water with aromatics. The smoking process and cured-bone chemistry create a distinctly smoky, sweet-salty depth absent in poultry or beef stocks. Its high gelatin content (especially when knuckles and feet are included) gives body and mouthfeel to the soups, braises, and sauces built upon it. This is a foundational building block in charcuterie-influenced and classical French regional cooking, not a finished dish.
The formula
1 kg smoked ham bones : 2.5 L cold water
Measured by bone weight; water is 2.5× the bone weight. Adjust aromatics proportionally: 150 g mirepoix (50% onion, 25% carrot, 25% celery) per kg bones. No added salt — the cure provides sufficient seasoning.
Identity
- Smoked pork bones simmered, not boiled, to extract gelatin and smoke compounds
- Mirepoix aromatic foundation — classical 2:1:1 onion-dominant ratio
- Bones blanched and rinsed before the long simmer to remove cure residue and blood proteins
- No added salt — the cure is the seasoning
- Strained through a fine-mesh chinois and cooled to below 4°C within 2 hours to ensure food safety
Ingredients
| Base | Smoked ham bones (knuckles, feet, hocks, trotters) | Knuckles and feet provide collagen and gelatin; hocks add meat for flavor. 500 g bones minimum for a small batch; scale up by weight. |
| Liquid | Cold water | 2.5× the weight of bones. Always start cold to promote gradual protein extraction. |
| Aromatics | Mirepoix (yellow onion, carrot, celery) | 150 g total per kg bones. Standard classical ratio: 50% onion, 25% carrot, 25% celery. Roughly diced, not minced. |
| Aromatics | Bouquet garni (bay leaf, thyme, parsley stems) | 1 bay leaf, 1 sprig thyme, 3–4 parsley stems per kg bones. Optional: 1 small clove-studded onion. |
| Seasoning | Black peppercorns | 4–6 whole peppercorns per kg bones. Added in the last 30 minutes to avoid bitterness from prolonged simmering. |
| Flavor | Tomato paste (for brown ham stock variation) | 1 tbsp per kg bones, sweated in fat before deglazing with water. Optional — adds color and umami depth for brown stock only. |
Method
- 1Rinse the smoked ham bones under cold water, scrubbing if necessary to remove surface cure residue and ash.Smoked bones carry salt and smoke deposits from the curing chamber; rinsing prevents over-salting and removes particulate ash.
- 2Place bones in a stockpot, cover with cold water by 5 cm. Bring to a full boil over high heat, then drain immediately, discarding the blanching liquid. Rinse bones and the pot briefly.Blanching causes blood proteins, myoglobin, and excess soluble salt to coagulate and dissolve into the first water, which is discarded. This clarifies the final stock and reduces salinity.
- 3Return blanched bones to the clean pot. Add 2.5× their weight in fresh cold water and 150 g mirepoix per kg bones. Bring to a boil, then reduce to the lowest possible simmer — a few lazy bubbles at the surface, not a rolling boil.A gentle simmer extracts gelatin from collagen without churning the liquid into turbulence that would cloud it. Starting cold ensures gradual, even extraction rather than a shock cascade of protein.
- 4Add the bouquet garni. Skim the surface vigorously for the first 15–20 minutes, removing all foam and fat that rises. After the initial aggressive skim, reduce heat to maintain a bare simmer for 3–4 hours total.The first-skim removes denatured blood proteins and fat emulsifiers that would cloud the stock. After 20 minutes, most proteins have already coagulated; continued gentle heat finishes extraction without re-emulsifying.
- 5Add peppercorns in the last 30 minutes. Strain through a fine-mesh chinois, pressing the solids gently with a ladle. Discard the solids.Straining removes all solids for clarity. Gentle pressing extracts remaining liquid; excessive pressure squeezes bitter compounds from the bones.
- 6Cool the stock to below 4°C within 2 hours using an ice bath or cold-water bath, then cover and refrigerate. Skim solidified fat after chilling if a leaner stock is desired.Rapid cooling through the danger zone (65°C–10°C) in under 2 hours is critical food-safety practice. Using an ice-water bath achieves this. Below 4°C, bacterial growth is inhibited. Fat solidifies on chilling, making removal effortless.
Techniques that matter
Blanching and refreshing
Two-stage cooking (blanch then simmer) is standard for all meat stocks. The first boil purges the bones of blood, myoglobin, and excess salt; the second simmer extracts flavor cleanly. Skipping this step produces a cloudy, excessively salty, bitter stock.
Bare simmer (frémissement)
True stock simmers at 85–92°C, not 100°C boiling. A rolling boil shears protein strands into the liquid, emulsifies fat permanently, and produces a cloudy, frothy result. The French call this frémissement — the surface trembling, not rippling.
Strain through a chinois
The conical fine-mesh strainer removes even micron-scale particles that a standard sieve misses. A stock is only as clear as its straining. For ultra-clarified versions, a raft of egg whites can be used, but this is not standard for a foundation stock.
Rapid cooling
In classical professional kitchens, stocks must pass through the danger zone (65°C–10°C) in under 2 hours total and reach below 4°C for safe storage. Using an ice-water bath or cold-water bath achieves this. Slow cooling promotes Clostridium botulinum spore germination in anaerobic conditions.
Variations & derivatives
White ham stock (fond blanc de jambon)Classical French
Prepared without tomato paste or browning; the bones are blanched and simmered directly. Result is lighter in color and flavor, used for delicate soups and sauces where the ham character is subtle.
Brown ham stock (fond brun de jambon)Classical French
Bones are roasted at 200°C for 30–45 minutes until caramelized before simmering, or tomato paste is sweated in fat and added. Produces a deeper amber color and more complex, roasted flavor. Used in cassoulet, navy bean dishes, and brown-sauce foundations.
Smoked ham hock stock (brodo di zampone)Northern Italy / Central Europe
Made primarily from smoked ham hocks simmered with celery, carrot, and onion. Richer in meat flavor, less bony. Used as a base for pasta e fagioli, minestrone, and ribollita.

Substitutions
- Smoked ham bones → Unsalted pork bones + 1 tbsp liquid smoke per 2 L stock — Liquid smoke replicates smoke flavor but lacks the salt-depth and chemical complexity of the cure. Adjust seasoning carefully; this is an approximation only.changes result
- Smoked ham bones → Smoked turkey legs or wings — Similar smoke profile, lighter body, mild turkey flavor. Works for turkey leg soup bases.
- Smoked ham bones → Chicken or pork stock + 1–2 g smoked salt per L — Approximation of smokiness and salt. The substitution lacks cure chemistry and gelatin contribution. Use for emergency only.changes result
Troubleshooting
Stock is too salty
Cure was excessively concentrated; bones were not blanched; blanching water was discarded insufficiently → Blanch bones in three successive waters (bring to boil, discard, repeat twice) before the final long simmer. Use younger, lighter-cured bones if available. Dilute with unsalted water or ice cubes made from unsalted stock.
Stock is cloudy
Boiling at too high a temperature, causing turbulence that emulsifies protein and fat into suspension → Strain through cheesecloth-lined fine-mesh strainer. Future batches: maintain only a bare frémissement simmer, never a rolling boil. Skim aggressively in the first 20 minutes.
Stock lacks body / gelatin
Using primarily lean shank or shoulder bones with little connective tissue; cooking time too short; bones were already fully exhausted → Add smoked ham feet or knuckles, which contain 6–8× the connective tissue of long bones. Extend cooking to 4–5 hours. A properly gelatinous stock will gel firmly when chilled.
Off, bitter taste
Peppercorns or aromatics cooked too long, especially with prolonged exposure to steam and heat; bones burned at the bottom of the pot → Add aromatics and peppercorns only in the last 30–60 minutes of the simmer. Use a heavy-bottomed pot and keep heat low enough that bones never contact a direct flame.
