Trim any uneven edges from your pork belly and weigh it. If it's close to 3 lb, proceed with the cure quantities listed. If it's more or less, use our cure calculator to adjust the ingredients by weight. Mix the cure by combining kosher salt, Prague Powder #1, brown sugar, maple syrup, and optional black pepper until fully blended.
Rub the cure evenly over the pork belly, making sure all surfaces are coated. Seal it in a vacuum bag or zip-top bag, pressing out as much air as possible.
Refrigerate for 7 days, flipping the bag once per day and gently massaging to redistribute the cure and liquid.
After curing, remove from bag and rinse the pork belly thoroughly under cold water and pat dry. Fry a test slice. If it’s overly salty, soak the slab in cold water for 1–2 hours and test again.
Place the slab on a wire rack set over a tray and refrigerate uncovered overnight to dry and form the pellicle, a tacky layer that helps smoke stick.
Smoke at 165°F using apple, cherry, hickory or your preferred smoke wood until the internal temperature reaches 150°F, about 5–6 hours depending on thickness.
Let the bacon rest for 30 minutes at room temperature, then refrigerate for at least 2 hours or preferably overnight to firm up for slicing.
Slice against the grain to your desired thickness. Edge pieces can be cubed for lardons.
