the hind leg of a pig above the hock joint, cut from the carcass and cured by salting and drying, and sometimes smoking, so that it will keep for months at room temperature. Gammon is the same joint as ham, but is left attached to the side during bacon curing, and cut from it afterwards. It is milder in flavour. ‘Ham’, in its more general meaning of the hind leg, is applied to cured meat made from other animals, including wild boar, mutton, goat, venison, and even badger.
The first records of hams come from the classical world. The Romans knew hams made by the Gauls in the last few centuries bc, cured by brining and smoking. Cato described how, in the 2nd century bc, the inhabitants of N. Italy made hams by layering legs of pork with dry salt, followed by drying and smoking.
In medieval times, hams were made all over Europe. Every cottager kept a pig, which was killed in autumn and preserved to provide food through winter.
Europeans took pigs and the art of curing meat to the Americas, where several types of ham developed. Another area of expertise in the curing of pork meat is China, especially the region of Yunnan.
Combinations of factors such as pig breed, feeding, curing recipe, and storage method gave rise to many varieties of ham. The process of curing all hams begins with salting. This may be done with dry salt or brine, or a combination of the two. Wet cures penetrate the meat more quickly. Saltpetre or nitrite (see salt) is added in small quantities to improve penetration and give a pink colour. After curing, which may take from a few days to several months, the ham is removed from the salt and dried. This operation may consist of hanging the ham in cool air, or may be aided by smoking. Some woods are particularly favoured; oak and hickory have a high tannin content which helps to preserve the meat, and aromatic woods can be used for a special flavour. Peat was used in Ireland. Certain European hams are finished over pinewood smoke, which forms a black, flyproof, resinous layer and flavours the ham slightly. During smoking, the hams lose about 25% of their weight.
Some of the most important types of hams are listed below, first those intended for eating raw, and then those which have been or will be cooked:
Hams which are meant to be eaten raw (see above) are cut in very fine slices, and served, depending on the region, with curls of unsalted butter, fresh figs, or melon.
The usual method of cooking a whole ham is gentle simmering in a large container. An old practice is to add hay to the cooking water, which is supposed to help reduce saltiness and certainly imparts a delicate flavour. Alternatively, a ham can be partially simmered, then baked; or, exceptionally, baked from the start.
The English method for dealing with hot boiled ham is to glaze it with brown sugar and mustard or fruit juice, and decorate by scoring the fat in a lozenge pattern and studding it with whole cloves. Sweet glazes are also popular in N. America, and fruit such as pineapple or peaches are used as a garnish. Creamy sauces flavoured with wine or mustard are favoured in continental Europe.
English boiled ham to be eaten cold has toasted breadcrumbs pressed over the fat to make a coating.
Ham goes well with eggs and pulses, as in the English combinations of fried ham and eggs, and pea and ham soup. Variations on these themes are to be found in most European countries. A little ham goes a long way; thus some stock, bones, or a little meat are sufficient to flavour hefty amounts of dried peas or lentils. Small pieces of ham are also added to some potato dishes. In Italy, it is used in sauces and garnishes for pasta, and numerous S. European recipes begin with chopped onions and ham lightly fried together.
