Got the 2lb bag.
Pretty spensive, but, figure if it works fine, Tp4 can get it from tractor supply brine tank version, which is wayyyyyy cheaper.
It's 100% KCl
Internet says it's safe to replace NaCl as long as you don't have kidney problems or take certain medication.
Taste, not as salty as salt, maybe 80%-ish, has a slight bitter aftertaste, definitely can't notice the aftertaste in a stir fry, but it's there.
