Pieces that are very appreciated. You can also find it in high quality hams and with Designation of Origin (Teruel, Huelva or Guijuelo, some of them that will sound familiar to you.)

That is why we are going to go deeply into the origin of the Duroc or Duroc-Jersey breed and its specific use in Spain.

1. Which is the origin of the Duroc ham?

Duroc ham emerged in the 19th century through the crossing of the Old Duroc and the Red Jersey breeds in the USA. These two breeds come from different European pigs such as the Berkshire or African pigs, such as the Colorado of Guinea. The Duroc breed genetically has more similarities with Iberian pigs than with white pigs.

In Spain they were introduced in the 60s and for some time now, they are being used in white pig crossings because they provide fat infiltration and improve their quality and flavor. This is the only breed allowed within the Iberian Quality legislation in force for crossing with Iberian pigs as long as it is limited to 50% of its origin and only through male.

We can say that the 50% of the products that are labeled as Iberian in our country come from the crossing of Iberian mother and Duroc father, although nothing is indicated on the label. This may cause detriment of pure iberico pieces to the consumer and to the manufacturer.

Gastronomy using Duroc hams

Due to the privileged genetics of these animals, Duroc hams are present in almost 90% of the high quality hams marketed in the world. About Spain, we can say that it is one of the most common in meat production thanks to its exceptional flavor, aroma and juiciness.

But also, thanks to all these qualities, its presence is gaining more strength in the gourmet cuisine of the world. It is ideal for preparations that require long cooking times, such as stews and roasts.

Another of the most commercialized parts of the Duroc pigs is the loin. The meat from the lower part of the neck has a lot of infiltrated fat, giving juiciness.

Duroc pigs are juicier, more tender in texture and more intense in flavor, ideal for both stews and grilled dishes thanks to its high fat infiltration. Its meat is also present in the production of hams, loin and other sausages that we consume regularly and it is mixed with white pork.

3. What are the differences between the Duroc pigs and the white pigs?

Duroc Pig

Duroc pigs are medium in size, with a reddish color and long hair. The trunk is of medium size, counting with long and moderately thin legs and black hooves.

Its meat of Duroc hams is very similar to that of the Iberian pig in terms of nutritional and organoleptic characteristics.

White pig

The most common white pig breeds to make serrano hams for human consumption are Landrace, Large White and Pietrain. They are animals with thick and short legs, with a characteristic pink or light and delicate skin, that can even burn if exposed to the sun.

Although it may appear that their meat contains a high level of fat, actually white pigs have lost the ability to accumulate subcutaneous fat and therefore do not infiltrate their muscles either. The meat of serrano hams is leaner but has less flavor.
