I keep my Num desserts in the freezer so I can grab one whenever the cravings hit. The instructions for freezing suggest either thawing to room temp, or warming and I definitely recommend warming. It changes the flavor for the better! And this goes for all of the items in the sample pack. I also really like the variety this pack has to offer. I didn't think I'd like the ginger cookies as much as I did, and they ended up being one of my favorite items in the whole pack. I'm just sad now that all my items are gone and I'll have to wait for more to arrive.
