Waiting for someone else to reply to this and maybe offer more experienced opinion.
I would think you could, I am not sure you would get much pellicle formed in the fridge because of the environment but maybe, with the frost free stuff it would work. I have done mine in the fridge in our rv a time or two but I am able to put a small fan in there to circulate the air and it is not frost free.
Maybe you could keep in fridge over night and them leave them out for a while under a fan to get some pellicle and bring up to room temps before putting into the smoker?
I am sure someone else will chime in!
