The following was learned from the USDA and a few universities. Important as you are intending to cold smoke. The semi cures are fine if you intend to hot smoke. How you cure is entirely your choice but, the forum does encourage sticking to the USDA guidelines.
Posted in another forum. Very simple math.
Having nearly 60 years of smoking foodstuffs and 40 years of curing pork bellies, I in no way consider myself an expert at either and far from perfect. After much research on the proper amount of time taken to fully cure pork belly using Morton Tender Quick. It was decided to talk to the USDA directly. After doing so, I was reassured, once again, that my method of curing pork belly was spot on. The USDA representative I talked to recommended when curing pork belly with MTQ, using the dry rub method, that the 7 day per inch thickness guideline is used (14 days for two-inch thick slab). This guideline is the same recommended by Morton. As I only use the dry rub method on pork bellies, no other method, cut of meat, or cure was discussed other than time sequences.
Notable notes:
1. The main determination in cure timing is the method in which pork bellies are cured. Core injection being the fastest, then brining or immersion process, while curing with a dry rub takes the longest amount of time to achieve a full cure.
2. Nitrite reacts with myoglobin or muscle cells only, not fat.
3. Salt in a cure adds flavor to the fat while reducing the water activity (aw).
