You may not have heard of guanciale, but it could be the reason your pasta dishes sometimes feel a bit lacking. A key ingredient in popular Italian dishes like spaghetti alla carbonara and pasta all'amatriciana, it is often replaced by pancetta or even back bacon, much to the consternation of Italians everywhere.
Guanciale is a highly-flavoured cured pork taken from the cheek or jowl of the animal, with its name derived from the Italian guancia, or cheek. It is cured using salt, pepper and spices, and has a high fat-to-meat ratio, giving it an intense, sweet-savoury pork flavour and a tender, melting texture.
The closest thing to guanciale is probably pancetta, which is cured belly meat, but there is still a notable difference between the two. Guanciale has both a richer flavour and a softer texture than pancetta or bacon, so if you like pancetta, you’ll love guanciale.
A specialty of central Italy, particularly Umbria and Lazio, guanciale is made by rubbing the fresh cut of meat, with the skin still on, in sea salt and spices, which typically include ground black or red pepper, thyme or fennel, and sometimes garlic. The meat is then left to cure for anywhere between three to ten weeks, and will lose 30% or more of its original weight.
