I won't use Tenderquick myself... don't see a need for using Nitrate on a short cure and since it's in Tenderquick, I just don't want to use it. I'm not going to second guess the USDA, so I see no reason at all to add Nitrate into a product that I'm curing for 2 weeks or less.
In addition to not wanting Nitrate added in my short cure , the ratios of salt to Nitrite are such that it it just doesn't give me the flexibility that I want. It's easy enough to get some Cure #1, or Cure #2, that I don't feel compelled in any way shape or form to use TenderQuick.
