B y untreated Back Pork Bacon I mean meat taken from the back of the pork before it is cured, smoked and made into what is called bacon. This untreated part of thr pig is delicious when grilled on high heat on a stove-top grill.. If you don't have a stove-top grill I would recommend you get one especially if you use gas to cook with. It is very useful for grilling steaks, fish, chicken etc. The only problem is that it is a pain in the neck to wash afterwards...but what the heck...life is not easy anyway! So, if you happen to buy a whole slab either ask your butcher to cut into 1 inch wide slices (safer) or you can do it at home but be careful not to cut yourself as I did,very badly, the other day (one of the hazards of cooking). Back bacon here is preferred to pork belly because back bacon has a 15% fat to 85% lean meat ratio, while pork belly is very fat, 60% fat to 40% lean meat ratio. .
