I've watched lots of videos on how to prepare bone broths. However, I haven't found much information about making it directly from frozen bones.
I have understood that I should move frozen bones from the freezer to the fridge at least 1 day or 2 days before to be safe. (If I want to use them normal way)
Or that I should put those frozen bones in cold water for at least 1 hour before use.
But if I want to use them directly from frozen? Can I? (without roasting them, directly just like that)
If I use a Pressure Cooker, on Low or High Pressure, I don't think there is any problem.
But if I want to use a Slow Cooker?
Generally, for frozen meat, they advice to set on High (Slow Cooker) for 1 hour and then move to Low.
But is it safe to do the same with frozen bones? From a bacterial point of view? Or should I boil them in a stove pot before (for how long?) and then transfer them to the Slow Cooker?
Maybe I'm overthinking it too much but I prefer to understand the process if possible.
Thanks for your help.
