I know "uncured" meats (like bacon and sausage) end up using celery and/or celery salt to bring the relevant chemicals, and "uncured" is a term with legal meaning that the makers of those products need to use. I wouldn't be shocked if someone had worked out a recipe for corned beef that did similar things, but labeling such a recipe "nitrate-free" would be misleading, if not actually incorrect.As an addendum, if you see any recipes for “nitrate free” corned beef which use regular salt in the brine, it won’t work. Sodium nitrate effects a chemical change in the meat - making it delicious. If you’re going to use a regular brine it will just taste like salty pot roast.
This is not me arguing about whether the nitrates are necessary--I'm completely willing to agree they are.
