Berliner Eisbein mit Erbspüree (Pork Knuckle with Pea Purée)
Why this recipe works
- Gentle simmering: Slow, steady cooking softens the skin and connective tissue while keeping the pork moist and tender.
- Smooth pea purée: Blending hot peas with butter creates a vivid, creamy side that balances the richness of the pork.
- Mustard for balance: Serving mustard at the table adds sharpness, cutting through the savoury broth and fatty pork.
- Good for planning ahead: The pork can be cooled in its cooking liquor and reheated gently, making the long simmer easier to manage.

Timing notes
- Mostly hands-off cooking: The active preparation is brief; the main time commitment is the gentle simmer needed to make the knuckle tender.
- Cook the peas last: Prepare the pea purée close to serving so it stays bright green and smooth.
- Rest before serving: A short rest after lifting out the pork helps the meat settle before it is served with the purée.
Authenticity notes
- Berlin-style Eisbein: Unlike crisp-roasted pork knuckle, Berliner Eisbein is simmered until soft and tender, commonly served with pea purée and mustard.
- Aromatic cooking liquor: Onion, carrot, celeriac, bay and peppercorns season the pork as it cooks and create a useful broth for serving or reheating.
Common mistakes
- Boiling too hard: Keep the pot at a steady, gentle simmer; a rolling boil can tighten the meat and make the broth cloudy.
- Watery pea purée: Drain the peas well and add reserved cooking water gradually, only as needed to loosen the texture.
- Serving without broth: If the pork looks dry after resting, spoon over a little hot cooking liquor for extra juiciness.
Make-ahead tips
- Keep components separate: Refrigerate the pork and broth separately from the pea purée so each reheats cleanly.
- Reheat gently: Warm the pork in its broth until piping hot, and reheat the purée over a low heat with a little water if it has thickened.
- Freeze with broth: For freezing, pack the cooked pork with some cooking liquor to help protect its texture during storage and reheating.

Pork knuckle
Pea purée and to serve
Instructions
- Rinse the pork knuckles under cold water. Peel the onion, carrots and celeriac, then cut them into large chunks so they hold their shape during simmering.
- Put the pork knuckles in a stockpot and add the onion, carrots, celeriac, bay leaves, peppercorns, salt and parsley. Cover with cold water by about 3 cm, then bring to a gentle boil and immediately reduce to a steady simmer.
- Simmer very gently for 2 hours, skimming any foam in the first 20 minutes. The knuckles are ready when the skin is soft and the meat pulls easily from the bone.
- About 10 minutes before serving, cook the peas in a saucepan of boiling water until tender and bright green. Drain well, reserving a splash of the hot cooking water.
- Blend the peas with the butter until smooth, adding a little reserved cooking water to loosen if needed. Taste and adjust with a pinch more salt if you like.
- Lift out the pork knuckles and let them rest for 5 minutes, then serve with the pea purée. Offer the mustard at the table, and spoon over a little of the hot cooking liquor if you want extra juiciness.
Recipe notes
Tips
- Keep the simmer very gentle; a hard boil can tighten the meat and make the broth cloudy.
- For a smoother purée, blend while the peas are still hot and drain them thoroughly so it stays vivid and not watery.
- If serving vulnerable people, make sure the pork is cooked until the meat is very tender and piping hot throughout.
Substitutions
- Replace Mustard with Bavarian sweet mustard for a milder, sweeter finish.
- Replace Unsalted butter with Salted butter, then reduce the Fine sea salt slightly when seasoning the purée.
Storage
- Refrigerate up to 3 days
- Cool the pork and broth quickly, then refrigerate separately from the pea purée. Reheat the pork gently in the broth until piping hot; reheat the purée over a low heat, stirring often, and add a spoonful of water if it thickens.
