Traditional...nitrates or nitrites?
Nitrate is traditional, and natural.
In curing, the good bacteria help the nitrate ferment and it is converted into nitrite which then converts into nitric oxide which reacts with myoglobin proteins and imparts the dark red cured meat color.
Prague Powder #1 (TCM (tainted curing mixture), pink salt, the pink shit) is 6.25% sodium nitrite. It is pink so that you don't confuse it with table salt. If you consume more than 2 oz. it will keep your blood from getting oxygen and you will slowly suffocate. You will have a nice rosy complexion upon your death and yet will paradoxically taste “cured.” It is used for fresh cured meats that are cooked or smoked or whatever above 155 F and imparts a characteristic cured flavor associated with hams, salami, bacon...etc.
Prague Powder #2 is 6.25% sodium nitrite and 4% sodium nitrate.
Naturally occurring mineral potassium nitrate or saltpeter has been traditionally used by western civilization to cure meats for, oh, the past 1600 years or so. The chemical compound salt sodium nitrate (#1) has less explosive properties than #2 and make it more reliable for curing meats. Nitrate breaks down more slowly than nitrite and is primarily used for longer dry cured applications which are not heated high enough to kill trichininosis. It also prevents oxidation and more importantly, like #1, the growth of the bacteria that causes botulism. Nitrates are limited to less than 3oz. per 100 lbs or you will be dead. #2 should never be substituted for #1, especially if the product is cooked at a high temperature. Nitrosamines may form and they may cause cancer, though the The National Research Council of the National Academy of Sciences has concluded that neither nitrite nor nitrate are carcinogenic.
Like helmets, one probably doesn't need curing salt and won't look traditionally "cool", but they have a purpose and do not hurt.
