McClelland's, in general, benefit from some "open tin time".
Dark Star is very compressed and will hold moisture for an incredible amount of time.
I like to open the tin, date the lid and come back at 1 month, 2 month, 3 month, etc ...
My last tin was sublime at 5-6 months and STILL required dry time.
Like many others, I prefer the cube cut method with a simple gravity pack.
Good Luck! :
