Also known as Prague Powder. It is dyed to easily identify it from regular salt. The makeup is 6% sodium nitrite and 94% table salt. Sodium nitrate helps both to prevent the growth of bacteria (in particular, botulism) and to preserve the original color of the meat. Use 1 ounce for every 25 pounds of meat, as more may cause the meat to become overly salty. Prague powder should not be used in place of table or seasoning salt.
