If you're giving the gift of a tin of freshly baked biscuits, the last thing you want is for your recipient to open it up to find the contents all dry and crumbled in the tin. America's Test Kitchen offers up a foolproof way to keep them moist for the long haul: Pack them with tortillas.
The video above does all of the explaining here, so it's worth a quick watch. You'll need both flour tortillas and parchment paper; while the paper will serve to separate the layers, the tortillas will provide a little extra moisture and cushioning to keep the cookies in one piece. And, as ATK notes, your gift recipient gets bonus tortillas.
