Did you check the FAQ?
The taste of DMT is usually a mixture of natural DMT (indole-based chem structure) smell, plus residual solvent. Redissolving the DMT in clean acetone/ethanol and re-evapping will help get rid of solvent traces, though it also might make your DMT a bit waxier, it doesnt crystallize in nice shapes like with naphtha.
The other possibility is making your DMT into fumarates with FASA or FASI, then converting the fumarates to freebase with BLAB tek's water crystallization (DMT will smell much milder like this).
As for freezer container, anything you can close (to prevent naphtha vapors "infusing" your freezer), and that you can later scrape your crystals out, is all good.
Be sure to do a few cycles of thorough mixing before pulling out the solvent each time, for good yields, thats a key. Also check FAQ for tips on how to retrieve crystals after freezing, etc.
