Re: Is there a trick . . .
I use a vortex and pack it just under the phunel bit, use 2 layers of single foil, loads of tiny holes and have 2 CC coals on with a windcover when needed.
Make sure you let the bowl heat properly before you start smoking, i sometimes leave the coals on for 5-10 minutes and move it around before i take a pull.
Practice makes perfect, see what works for you
