Re: Best way to poke holes in the foil?
For a loose pack i do 3 concentric rings with 3 or 4 in the center. If I've overpacked then I punch 4 or 5 holes right through the holes in the bottom of the bowl and use the tool on the tongs to open them up for good airflow. Then I usually punch about 8 more smaller holes around the perimeter. Works very well for me. Since I almost always overpace these days I use this method most often. Smoke happy.
