Christmas Ham
Also: Finnish Christmas Ham, Joulupöydän kinkku
A whole bone-in pork leg, salt-cured and slow-roasted at very low heat for many hours, finished with a sweet-sharp mustard-and-breadcrumb glaze that bakes into a golden crust — the centrepiece of the Finnish Christmas table.
Identity criteria
- 1Whole bone-in pork leg; no secondary cuts or boneless formats
- 2Salt-cured before cooking — curing is not optional seasoning but structural to the dish's identity
- 3Slow-roasted at low temperature (80–100 °C) for a minimum of 1 hour per kilogram, often overnight
- 4Finished with a coating of Finnish sweet mustard (sinappi) and fine dry breadcrumbs, then briefly high-heat-baked to form a firm golden crust
- 5Served as a feast centrepiece at Christmas (jouluateria); outside that context it is simply roast ham
- 6Accompanies the traditional Finnish oven-casserole trinity — lanttulaatikko, porkkanalaatikko, perunalaatikko
Components
whole bone-in pork leg (5–10 kg)essentialBone-in is canonical; the bone conducts heat and contributes body to any resting juices
whole peppercorns, bay leaf, allspice berriesoptionalTraditional in the curing brine or boiling liquid (historical method); impart background warmth
pork skin and subcutaneous fat capessentialScored in a crosshatch before roasting; renders slowly and bastes the meat throughout
water or stock for roasting vesseloptionalA small amount prevents scorching during the long low roast; absorbed by the fat drippings
Finnish sweet mustard (sinappi)essentialApplied hot from the oven to act as adhesive for breadcrumbs; mild, slightly sweet character is non-negotiable
fine dry breadcrumbsessentialCoats the mustard layer and crisps under high heat to form the defining crust
salt cure (coarse salt, sugar, sodium nitrite)essentialWet or dry cure applied days in advance; gives the characteristic pink interior and ham flavour
egg wash (beaten egg)optionalSome families brush egg over the surface before mustard to reinforce adhesion of the crust
Technique
- Salt curing
- Transforms raw pork into ham — develops the characteristic pink colour, preserves texture under the long roast, and builds the sweetly saline flavour depth that distinguishes joulukinkku from plain roast pork
- Low-temperature slow roasting (80–100 °C)
- The extreme length and low heat render the fat cap without tightening the muscle fibres; the internal temperature rises to ~77 °C while the meat remains tender and juicy — high-heat roasting produces a dry, tight result that is a canonical failure mode
- Crosshatch scoring of the fat cap
- Allows fat to render evenly, creates channels for the mustard-breadcrumb coating to anchor, and gives the finished crust its decorative diamond pattern
- Mustard-breadcrumb glaze and high-heat finish (225–250 °C, 20–30 min)
- Converts two inert coatings into a brittle, flavourful shell via Maillard browning; the transition from slow to high heat is abrupt and intentional — gradual temperature rise causes the coating to dry out before browning
Form & serving
- Served
- Sliced at the table from the whole leg; traditionally carved cold the next day as well
- Temperature
- Warm when freshly roasted; equally traditional served at room temperature or cold as leftovers throughout the Christmas period
- Portion
- Centrepiece for 8–20 people depending on leg size; carved thickly
- Pairs with
- lanttulaatikko (rutabaga casserole) · porkkanalaatikko (carrot casserole) · perunalaatikko (potato casserole) · lingonberry jam · Finnish sweet mustard (additional, for serving) · pickled cucumber or beetroot · dark rye bread
Character
Flavour
Texture
Tender and moist interior with a firm, slightly crunchy golden breadcrumb crust and a rendered, lightly crisped fat layer beneath
Eaten
Formal Christmas Eve or Christmas Day feast (jouluateria); the ham is placed whole at the centre of the table and carved communally, surrounded by the casserole dishes and condiments; leftovers are eaten cold on sandwiches with mustard for days after Christmas
When
winter
Variations & related
Regional variations
- Keitetty kinkku (boiled then glazed) · Finland (older tradition)
Ham is simmered in spiced water for several hours before the oven glaze finish; produces a softer, more uniform texture; largely displaced by the all-oven method but still common in older households
- Honey-mustard glaze variant · Finland (contemporary)
Replaces or supplements the sweet mustard with honey; slightly stickier crust, acceptable modern variation that does not break identity
- Sous-vide joulukinkku · Finland (modernist home cooking)
Long low-temperature water-bath replaces oven slow-roast; achieves similar internal result but lacks the rendered fat-cap character; the glaze finish is unchanged
Related dishes
- sibling Julskinka (Swedish Christmas Ham)
Near-identical Scandinavian tradition; Swedish version typically uses a slightly different mustard-and-egg glaze and is more commonly boiled
- sibling Juleskinke (Norwegian Christmas Ham)
Norwegian variant, usually boiled and glazed; part of the shared Nordic Christmas pork tradition
- ancestor Salt-cured pork leg (Nordic medieval)
The practice of curing and reserving a whole leg for Christmas predates the modern glazed form by centuries

Rutabaga casserole is the canonical savoury companion on the Finnish Christmas plate
- pairs-with Porkkanalaatikko
Sweet carrot casserole; part of the obligatory casserole trio served alongside
Substitutions
Finnish sweet mustard → Dijon or coarse-grain mustardinadmissible
Changes flavour profile significantly — Finnish mustard is milder and sweeter; sharper mustard is more pungent and can overwhelm the breadcrumb crust
fine dry breadcrumbs → pankoinadmissible
Panko is too coarse and airy; does not adhere uniformly and falls off when sliced
fine dry breadcrumbs → gluten-free breadcrumbsadmissible
Functionally equivalent for the crust; safe textural swap that preserves identity
whole bone-in leg → boneless ham jointinadmissible
Loses the structural and flavour contribution of the bone; acceptable for smaller households but not canonical
salt cure (home-cured) → pre-brined supermarket hamadmissible
The vast majority of Finnish households buy a commercially cured leg; functionally identical for home cooking
egg wash under glaze → omittedadmissible
Egg wash is optional; omitting it is common and does not break the dish
Common mistakes
- Roasting at too high a temperature (above 125 °C) which seizes the muscle fibres and produces dry, tough meat
- Applying the mustard-breadcrumb glaze to a cold or partially cooled ham — it will not adhere properly and steams rather than crisps
- Using sharp Dijon or wholegrain mustard instead of mild Finnish sweet mustard, producing an aggressively pungent crust that overwhelms the pork
- Skipping the crosshatch scoring of the fat cap, resulting in the glaze pooling unevenly and the fat failing to render
- Insufficient curing time before roasting — a pre-brined commercial ham can go straight to the oven, but a home-cured leg needs at least 3–5 days of cure time
- Treating the dish as a quick weeknight roast — a 7 kg leg at 80 °C needs 7+ hours; undercooking leaves the centre under temperature and the fat un-rendered
- Carving immediately out of the oven — the ham must rest at least 30 minutes for juices to redistribute before the first slice
Provenance
Joulukinkku has been the cornerstone of the Finnish Christmas table since at least the 18th century, when pork was slaughtered in autumn and the cured leg reserved for the midwinter feast. The mustard-breadcrumb glaze became standardised in the 20th century as commercial sweet mustard production grew. The dish is entirely settled as a Finnish tradition with no meaningful competing claims.
