Jambon Persillé Recipe

Prepare the meat

Trim excess exterior fat from the pork leg or shoulder, leaving some fat for flavor. If using a bone-in cut, keep bone intact (it will add collagen). Tie the meat with butcher twine at 3–4 cm intervals to create an even cylinder for slicing later. Season the exterior lightly with the 2 tsp salt.

Make the poaching/stock liquid

In a large stockpot, combine 2.5 liters cold water, chopped carrot, quartered onion, chopped celery, bay leaves, whole peppercorns, and garlic cloves. Add the optional 120 ml white wine if using. Bring to a gentle simmer over medium heat (do not boil vigorously).

Poach the meat

When the liquid is simmering, gently lower the tied pork into the pot. Reduce heat to maintain a bare simmer. Poach gently until the meat is very tender and a thermometer inserted to the thickest part reads about 68–72°C (155–162°F) and it pulls easily, about 1 hour 45 minutes to 2 hours depending on size. Skim any foam that rises to the surface periodically.

Cool and reserve stock

Carefully remove the meat from the poaching liquid and let cool slightly. Reserve the cooking liquid; strain it through a fine sieve or cheesecloth into a bowl. Chill the strained stock in the refrigerator until fat rises and the liquid begins to set slightly (at least 2 hours).

Reduce stock for stronger gelée (optional)

If the stock seems weak, skim fat and reduce the strained stock in a clean saucepan over medium heat until you have about 500–600 ml concentrated flavorful stock (about 20–30 minutes). Taste and adjust seasoning, remembering this will become the gelée base.

Prepare parsley and slicing

While stock chills, finely chop 1 cup fresh parsley and thinly slice the cornichons. Spread out the chopped parsley to check for uniform small pieces — these will create the characteristic green flecks in jambon persillé.

Bloom the gelatin

Pour 120 ml cold water into a small bowl and sprinkle 25 g powdered gelatin evenly over the surface. Let stand 5–10 minutes until gelatin blooms (absorbs water and becomes spongy).

Dissolve gelatin into warm stock

Gently heat 400–600 ml of the chilled, strained (and reduced if used) stock until warm but not boiling. Stir in the bloomed gelatin until fully dissolved. Taste and adjust with up to 1 tsp kosher salt, 1 tsp freshly ground black pepper, and optional 1 tsp lemon juice. Stir in 2 tsp Dijon mustard for subtle flavor. Remove from heat and let cool until slightly viscous but still pourable (about 20 minutes).

Assemble the terrine

Slice the cooled poached pork into 1 cm thick slices or break into large irregular pieces if you prefer more rustic texture. Line a 900 g to 1 kg terrine mold or standard loaf pan with plastic wrap so edges overhang for easy removal. Arrange a layer of pork pieces along the bottom and sides, pressing to leave minimal gaps. Sprinkle a layer of chopped parsley and some cornichon slices between meat layers so green flecks are visible throughout. Repeat layering until the mold is filled, finishing with a decorative layer of parsley and a few cornichon slices on top. Pour the slightly cooled gelatin-stock mixture evenly over the assembled meat, tapping the mold to eliminate air pockets. The liquid should just cover the ingredients; if not enough, warm a little more stock and dissolve additional gelatin in the same ratio (approximately 5 g gelatin per 100 ml stock).

Chill to set

Fold the overhanging plastic wrap over the surface or place a piece of parchment and a weight (a small plate with a can) on top to compress. Refrigerate for at least 6–8 hours, preferably overnight, until fully set and firm.

Unmold and slice

Run a small knife around the edges of the terrine, unwrap the plastic, and invert onto a cutting board or platter. If stuck, briefly dip the bottom of the mold in hot water for a few seconds to loosen. Slice the jambon persillé into 1 cm thick slices with a sharp knife, wiping the blade between cuts for clean slices.

Serve

Arrange slices on a bed of lettuce leaves or salad greens. Serve chilled or at cool room temperature with extra Dijon mustard and cornichons on the side. Finish with a light grinding of black pepper. Keeps refrigerated, covered, up to 4–5 days.
