Hi, David.....I think you want Prague powder.... there are 2 generic putups in North America, marketted by whomever.
PP #1 is straight salt and sodium nitRITE to the parts per million reqirements. You add X nuber of grammes of PP#1 to get to the conentration for your product.
PP#2 is a blend of salt, sodium nitrite, and sodium nitRATE....for the formulae requiring a slow maturation time.
The Morton people market what they call tenderquick, and tendercure....this is sort of like prague powder, except they add sugar, and other seasonings, and want you to make up your entire salt content with their stuff. Dyed pink, to keep them apart from table salt.
Prague powder leaves you the flexability to vary your salt percentages, and seasonings, with still, the correct amount of nitrites in the mix...when you use the PP to the required rate. It's on the box.
Stuffers sells both. Go here,
