Tenderquick has both Sodium Nitrite & Sodium Nitrate @ 0.5% each, plus other ingredients. Unless you have a recipe that specifically asks for tenderquick; do not use it in place of Cure #1 (F.S. Cure or Sodium Nitrite @ 5%)
When curing bacon or ham it is best to use our All Purpose#2 Cure (Sodium Nitrite). This is a salty brine combination that is simple to use by adding water. If you have a recipe of your own that has salt included in it than you can use FS Cure (And Use Accordingly).
