I can view it on YT. Its a bit blurry but I am pretty sure he isn't removing the mace but the outer coating around the nut. It comes off in a rounded brown half shell like piece which looks nothing like mace. Mace is delicate and lacy and doesn't cover the entire surface of the nut. Apart from anything else it is very difficult to obtain nutmeg with the mace around it so it seems unlikely he would have it.
Sorry if I seem to be nit picking! I find it fascinating.
