Here is a guide to the different cuts of pork (the greatest meat with the greatest fat).

Jowl:

Not a very common cut of pork, but has its occasional  use.  It used used more in countries outside of the United State.  This cut is also referred as pig neck.  It is a very fatty piece of pork and should be cooked low and slow for long periods of time to render out the fat.  The result is a very tasty and juicy piece of pork.  One of the most unusual recipes including the Jowl is: Cracked Muffins (which I may have to try).

Pork Shoulder:

Consists of two main cuts the Boston Butt and Picnic, both are used for making pulled pork.  Additional cuts consists pork steaks, ground pork, pork shoulder roast, smoked hocks, and shanks.  The cuts from the shoulder are very fatty and best cook low and slow over a long period of time to render out as much of the fat as possible.  The result again are a very tender and juicy pork.  A common pulled pork recipe is the Renowned Mr. Brown.

Loin:

The loin contains some of the more common cuts of pork we buy at the grocery store.  The cuts include loin roast, rack of pork, pork tenderloin, center cut loin chops, pork loin, Canadian back, boneless pork loin, bone in pork chops, center cut pork loin, back ribs, and country-style ribs.  Most the these can be either cooked around fairly quick as these are some of the leanest parts of a pig.

Side:

Consists of the spareribs and bacon sections.  Other cuts include pork belly, St. Louis style spareribs, pork shoulder hocks, pork leg (fresh ham) hocks.  Cuts from the side are fairly fatty and again take advantage of low and slow cooking.  Pork belly is not a very popular cut of pork in the United States, but if cooked right it can be a very versatile cut of pork.  A sample recipe for pork belly is Slow roasted pork belly with pears.

Leg:

The main cuts of pork from this section is the cured ham and fresh leg.  Other cuts consists of pork leg (fresh ham) short shank, pork leg (fresh ham) boneless, coarse chopped pork, and pork cubed steaks.  This is the section where our holiday hams come from. 

Hind Feet (Pig's Feet):

This use to be considered a delicacy in the United States, but no more.  It is still in high demand in countries across the world.  Pig feet is actually not too bad for you as it provides more protein and less fat than country-style pork spare ribs.  A sample recipe for pig feet is Boiled Pigs' Feet Recipe.
