Step-by-Step Instructions

Step 1: Score, season, and sear the knuckles

Heat the oven to 160°C (320°F). Pat the pork knuckles dry. Using a sharp knife, lightly score the skin in a crosshatch pattern, spacing cuts about 1 cm apart and no deeper than 3 mm (avoid cutting into the meat). Rub the knuckles all over with salt, pepper, and paprika.

Heat the oil in a heavy oven-safe pot or Dutch oven over medium-high heat. Sear the knuckles on all sides until deeply browned, 3–4 minutes per side. Transfer to a plate.

Step 2: Build the beer braise

In the same pot, add the onion, carrot, and celery with a pinch of salt. Cook, stirring, until lightly caramelized, 5–6 minutes. Add the garlic and cook 30 seconds. Pour in the beer and scrape up any browned bits. Add the stock, apple, bay leaves, juniper berries, peppercorns, and marjoram. Return the knuckles to the pot, skin side up; the liquid should come about halfway up the sides (add a little water if needed). Bring to a gentle simmer.

Step 3: Braise until tender

Cover the pot and transfer to the oven. Braise for 2 to 2 1/2 hours, until the meat is very tender but still holds its shape and the internal temperature is around 90–95°C (194–203°F). Carefully lift the knuckles to a rack set over a tray to drain and dry. Strain the braising liquid; discard solids. Skim fat and reserve at least 360 ml (1 1/2 cups) liquid.

Step 4: Make the sticky lacquer

Pour 240 ml (1 cup) of the strained liquid into a small saucepan and reduce over medium-high heat to about 120–180 ml (1/2–3/4 cup), 8–10 minutes. Whisk in the honey, Dijon, whole-grain mustard, vinegar, and soy sauce (if using). Simmer 2–3 minutes more until glossy and syrupy enough to coat a spoon. Keep warm.

Step 5: Roast and glaze for crackling skin

Increase oven temperature to 220°C (425°F). Place the knuckles on a rack over a roasting pan, skin side up. Roast for 10 minutes to dry and crisp the skin. Brush generously with the glaze and continue roasting 10–15 minutes more, brushing once or twice, until the skin is lacquered, deep mahogany in color, and crackling. Watch closely to prevent burning. Rest 5–10 minutes.

Step 6: Warm the sauerkraut

While the knuckles roast, heat the butter and oil in a skillet over medium heat. Sauté the sliced onion with a pinch of salt until soft and translucent, 4–5 minutes. Add caraway, marjoram, and bay leaf; toast 30 seconds. Stir in the sauerkraut and grated apple. Moisten with 120 ml (1/2 cup) reserved braising liquid, then simmer gently 10–12 minutes until hot and fragrant. Balance with a pinch of sugar if needed; season with pepper and salt to taste. Keep warm.

Step 7: Make the caraway potatoes

Boil the potatoes in well-salted water until just tender, 12–15 minutes; drain well. Return to the warm pot with the butter and toasted caraway seeds. Toss over low heat until glossy and coated. Season with salt and pepper, then fold in parsley or dill.

Step 8: Plate and serve

Serve the knuckles whole or carve into large chunks. Spoon a bed of warm sauerkraut on each plate, top with pork, and brush with a little extra glaze. Add a side of caraway potatoes. Garnish with herbs and pass horseradish and mustard at the table.

Pro Tips

For extra-crackly skin, air-dry the seasoned knuckles uncovered in the fridge for 6–12 hours before searing.
Choose a malty lager or amber beer; very hoppy IPAs can turn bitter in the braise.
Don’t rush the glaze: reduce until it clings to a spoon—this is what creates that lacquered finish.
Keep the liquid level to halfway up the meat to avoid soggy skin during the braise.
Use a thermometer: 90–95°C (194–203°F) internal ensures tender meat that still slices.

Variations

Pressure cooker shortcut: Braise under high pressure for 45 minutes with natural release, then proceed to glaze and roast.
Dark beer twist: Swap in a malty bock or porter and use brown sugar instead of honey for a deeper caramel note.
Garlic-chile lacquer: Add 1 tsp finely grated garlic and 1/2–1 tsp chili flakes to the glaze for a gentle heat.

Storage & Make-Ahead

Braise up to 2 days ahead: cool knuckles in the strained liquid and refrigerate. On the day of serving, lift out, pat dry, warm gently in a 160°C (320°F) oven for 15 minutes, then roast at 220°C (425°F) while glazing until lacquered. Sauerkraut reheats well on the stovetop with a splash of water. Potatoes are best fresh, but you can parboil them 1 day ahead; reheat with butter and caraway. Store leftovers airtight: pork and sauerkraut up to 3 days in the fridge or 2 months in the freezer; re-crisp pork under a hot oven or broiler.
