These three pork products look alike, taste somewhat similar, and even get regularly substituted for each other. It's no wonder we get them confused! In actuality, they have very distinctive characteristics that make each ideal for different kinds of preparations. Here's the scoop...
Bacon (pictured directly above) and pancetta (top right) have the most in common. They are both typically made from pork belly and both are cured for a certain length of time. Both are also considered "raw" and need to be cooked before becoming palatable.
The process for making the two is slightly different. For pancetta, the focus is really on how it's cured. This can be done simply with salt, but spices and other aromatics are often added to infuse the pancetta with particular flavors.
Bacon takes things one step further by smoking the meat after it's been cured. This is usually a cold-smoking process, meaning that the bacon isn't actually heated or cooked during smoking and remains raw. Smoking can be done with a wide range of woods, from apple to maple, which each give their own distinctive, delicious flavors to the meat.
So pancetta is cured and unsmoked, while bacon is cured and smoked, but both need to be cooked before being eaten. They can be used interchangeably in dishes, depending on whether or not you want a smoky flavor. Make sense?
Prosciutto (top left) is very different from either bacon or pancetta, but we think it gets confusing because the words prosciutto and pancetta can sound similar to our non-Italian ears! Prosciutto is made from the hind leg of a pig (ie, the ham), and outside Italy, calling it prosciutto indicates a ham that has been cured.
The quality of prosciutto is is entirely in how it's cured. The outside of the ham is usually rubbed with just salt and sometimes a mix of spices. This draws out moisture and concentrates the flavor while the ham slowly air-dries (very much like dry-aged beef). This process can take anywhere from a few months to a several years depending on the desired result.
Once cured, prosciutto is usually thinly sliced and eaten as is. In other words, uncooked - though we wouldn't exactly call the meat raw after it's been cured for so long. Sometimes prosciutto gets lightly cooked as a finishing touch to a pasta sauce or other dish, but this is more to bring out the aroma and merge flavors than it is to cook the prosciutto.
So now we have to ask - between the three, do you have a favorite?

i'm a good old fashioned bacon girl.
proscuitto is a close second.
prosciutto, of course :)
In Italy they sell also 'prosciutto cotto' which is boiled (cotto means cooked), it's cheaper and not so good as the 'real' thing but always welcome in panini (and sandwiches). Actually, if ask for prosciutto in a supermarket or 'salumeria' shop, they will most probably ask you back: 'crudo or cotto?'
(= raw or cooked?)
BTW: prosciutto is pronounced with a sh sound in the middle (in Italian, 'sh' is spelled 'sci' before u, a and o)
I grew up eating pork bacon in KY, and never heard of pancetta or proscuitto until watching the Food Network when I was in college! Nowadays, I don't eat pork bacon very often, usually I eat turkey bacon. I don't eat proscuitto very often, just on the occasional anti-pasto plate. But I've discovered I really like pancetta. I actually just made soup with it this past weekend. The first step is to saute pancetta and fresh chopped fennel. The smell is INTOXICATING. This is my #1 favorite soup.
I prefer guanciale to pancetta. An even sweeter, porkier taste. Yum.
Judi, I was just about to post the same thing. I love guanciale, (which is cured hog jowl, and is a product typical of the area around Rome) but it is next to impossible to find in the states.
I have to agree with JudiAU.
Guanciale rules. It's extra fatty (pig jowel) and I love it so much I have it shipped to my house!
is there a difference between prosciutto and jambon de bayonne (or other french jambons crus?) other than region of origin?
