The pig has played the leading role in Spanish cuisine and culture, above all in rural Spain, where it has been a fundamental part of the meat diet. It is the only animal from which absolutely everything is used. Cured ham is the most important pork product obtained from the Iberian pig. The amount and composition of the fat are determining factors in the final quality of meat products and especially cured ham. It can be seen in the white streaks that appear and provides juiciness. Making ham begins with the curing process to eliminate moisture and achieve the natural fusion of the fats during maturing, when the aromas and flavours characteristic of cured ham appear. Products from Iberian pigs fed with acorns are also excellent.
