At the end of November or early December here in Murcia we often have a celebration called a matanza. A pig, that has been raised here in La Murta, is humanely slaughtered at a local abattoir and then returned to the villagers, where a skilled butcher will cut the meat and prepare it for different dishes, including salchichas.
The extended family and friends gather and enjoy breakfast together and watch the proceedings. Every part of the pig is used. The produce will be shared around the family and feed them through the winter months. Even the village cats get a little treat.
