A:
It's both. Standard soy sauce is very salty. That lowers the freezing point a lot, as discussed elsewhere on this site. I don't think it will be lowered all the way to -21°C, the freezing point for saturated salt water, but it might get close. Your freezer apparently can't quite get that cold. You might try a lower-salt soy sauce to see if it will freeze in your freezer.If it does, it will only partly freeze, leaving behind more salty liquid. Mike W.
