Combine the curing salt, maple syrup, brown sugar and pepper.
Rub the mix onto both sides of the belly.
Place in plastic bag on a pan in the refrigerator for 7 days. Flip the pork belly at least once a day..
After 7 days, remove pork belly from bag or pan and rinse off cure under cold water.
To smoke, fire up your smoker for smoking at 165 F. Use a fruit wood or hickory.
Add the belly to the smoker and smoke for 4-6 hours or until the internal temperature reaches 155 F. Remove and let rest for 10 minutes.
Slice lengthwise. If the belly is too soft to slice you can freeze it for 30 minutes to get it to set a little first.
To cook, fry in a pan or (my preferred method) bake in the oven at 400 F on an aluminum foil-lined pan for 30 minutes or until as crispy as you like it, flipping once.
Leftover bacon (cooked or raw) can be frozen for later use.
Notes
For best flavor, use vacuum-sealed bags for storage.
