One box (container?) of this is enough to last, me anyway, like 6 years. You don’t use more than a tablespoon of the shit at a time. I suppose if I were Korean I may use it more often. In the meantime it turned black essentially. It wasn’t moldy. So I used it. I couldn’t tell if it was not any good because it didn’t really have flavor, just hot. I didn’t die, so apparently it’s still good. Just not red anymore. Not that it was ever as red as it is depicted on the lid.
