Mexican Christmas pork loin: what it is and how to make it

What is it?

The Mexican Christmas pork loin is one of the most characteristic dishes of the Christmas Eve dinner on 24 December, especially in homes that prefer a more economical option than salt cod or a whole turkey. It consists of a whole piece of pork loin (1.5 to 3 kg) marinated in a mixture of red wine, prunes, sweet spices (cinnamon, clove, allspice), garlic and herbs, baked slowly until golden on the outside and juicy on the inside, bathed in a thick, dark prune sauce that surrounds the meat. It is served sliced at the table with the prune sauce, accompanied by mashed potato, roasted apple and Christmas Eve salad. Its sweet-savoury profile with spiced and fruity notes is one of the most loved on the Mexican Christmas menu.

Origin and history

The Christmas pork loin with prunes has a colonial origin in New Spain, derived from the Spanish techniques of marinating pork with wine, dried fruits and spices at Christmas religious banquets. Larousse Cocina notes that pork (Sus scrofa domesticus) arrived in Mexico with the 16th-century conquest and quickly integrated into the national cuisine, especially in festive preparations. The association with Christmas comes from the viceregal period, when well-off families served roast pork on Christmas Eve following European traditions. México Desconocido documents that the version with prunes and red wine became established in the 19th and 20th centuries as a Mexican urban banquet recipe, simplified from the Spanish loin with orange and the European loin with mustard. The formula with prunes is a Mexican adaptive invention, possibly influenced by the French recipes for canard aux pruneaux. Today it is a flagship dish of the Christmas menu in Mexican middle-class homes, a popular alternative to salt cod and turkey.

Characteristic ingredients

The preparation of the Christmas pork loin requires planning. The traditional cut is a whole pork loin (the central part of the back, lean and cylindrical in shape), weighing between 1.5 and 3 kg. The marinade combines dry red wine, prune juice or rehydrated and blended prunes, ground garlic, salt, pepper, cinnamon, clove, allspice, bay leaves and sometimes a touch of mustard or plum jam. The meat is marinated for 12-24 hours, refrigerated. For the baking, it is first seared in a hot pan with oil, browning on all sides; it is transferred to a tray with the marinade and baked covered for 1.5-2 hours at 160-180 °C, uncovering at the end to brown the surface. The sauce is made with the prunes rehydrated in wine and blended with stock, reduced to the desired consistency and served over the sliced meat. Mexican variants include loin with pineapple and chipotle, loin in Mexican adobo, loin with mole or loin with orange and chilli.

Cultural significance

The Christmas pork loin is an emblematic dish of the Christmas Eve dinner in much of Mexico, especially among urban middle-class families who seek an alternative more affordable and manageable than the whole turkey or the laborious salt cod. Its preparation is a family ritual of the afternoon of 24 December, with the house filling with sweet and spiced aromas during the long baking. It is served carved in generous slices, presented on a platter with the prune sauce drizzled over it, accompanied by sides that provide colour and contrast: creamy mashed potato, roasted apple with cinnamon, pink Christmas Eve salad, warm bread rolls. The Mexican pork economy has significant peaks in December because of the demand for the Christmas loin. Traditional Mexican cuisine was recognised by UNESCO as Intangible Cultural Heritage in 2010, and Christmas dishes such as the loin are part of the contemporary gastronomic heritage, an expression of mestizaje and constant adaptation.
