This curing salt is composed of 94% and 6% sodium nitrite and goes by many names:
• Pink curing salt
• Instacure #1
• TCM - Tinted Cure Mix
• Prague Powder I
This curing salt mixture is pink in color. It will imbue most meats with a rich, pink color, and helps to prevent bacteria such as Clostridium botulinum, the bacterium that causes botulism, from growing on the meat.
This is strong stuff - make sure you wear food preparation gloves when you handle it.
