This Portuguese cured ham is similar to Spanish jamón and Italian prosciutto. Presunto is a modern continuation of the ancient tradition of curing meat, a process that protects the nutritional value, flavor, and texture of the original ingredient.
The first written records of the production of cured ham are from a 300BC description by Roman historian Cato the Elder. At the time, the process was somewhat different and included large amounts of salt, which affected the final flavor of the meat.
The leg is then left to dehydrate and age for months until it achieves the right texture, moisture, and aroma. The earliest evidence of presunto dates back to Roman times, however the Phoenicians are believed to have been the first to bring pigs to the Iberian peninsula.
These pigs later interbred with the native wild boars, resulting in the modern-day Black Iberian pig. There are many different varieties of presunto, but the most prized version is made from this variety of pig, which is raised on large fields and fed only acorns, wild herbs, and roots.
Six local varieties of this Portuguese delicacy are protected under European law with geographical indications, and all of them are supposed to be enjoyed sliced into thin, nearly transparent strips. The cuts should always be parallel and equally proportioned, and they should be well-marbled.
