Make Smoking in pot

Here are some ways to make smoking!

1st,

Put chips in a pot directly without separating poultry (meet).

Using this way, smoke works on foodstuff  very well

but

products are burn.

2nd,

Separate chips and foodstuff with tin foil.
The foil has some small holes.

This way, meet isn't burn,

but

smoke doesn't work well.

3rd,

Smoke meet with tin foil without holes.

In this way, I made some interstices between pot and foil.

No burn and smoked well.

The 3rd way is the best to smoke without smoking device.
