Be careful not to use too much. Morton's Tender Quick has less Nitrite than Prague Powder No. 1 (AKA Insta-Cure No. 1 or Cure No. 1) and may be easier to use in small batches. Prague Powder is 6.25% Sodium Nitrite and is way too concentrated to use directly. Tender Quick is 0.25% Sodium Nitrite and Morton has directions for use on the package. Prague Powder No. 2 contains Sodium Nitrate in addition to Sodium Nitrite and is intended to be used where there is a long curing time.
