Should i wait for it to thaw out before i start my cure or would it be OK to start?
I would thaw it.
Yeah, throw it in the fridge for a couple-three days and it should be thawed enough.
I would thaw it out as well.
Thaw it.
If there is one thing i have learned on this forum it is that the colder the enviroment the meat is in the slower/longer the curing process.
so the best thing you can do is thaw and keep the meat in a fridge that will not be opened and closed a lot.
around the 38 degree mark.
