FAQ
How long can you freeze miso?
Freezing miso is not recommended; texture breaks down or the result is unsafe to rely on.
How do you thaw frozen miso?
Safest. Allow about 24 hours per 5 lb (2.3 kg); small packs thaw overnight. Once thawed, raw meat and seafood keep 1–2 extra days in the fridge.
Can you refreeze miso?
Only if it was thawed in the fridge and has not been left out. Quality drops each time.
Does freezing kill bacteria in miso?
No. Freezing pauses bacteria; they become active again as the food thaws. Cook or reheat to a safe temperature.
