Cold Smoking Basics
The secret to effective cold smoking is patience and temperature control. You are not cooking; you are conditioning the surface of the protein to accept layers of smoke over several hours.
Keep it cool or keep it out
The ambient temperature must be below 70°F, ideally in the early morning or late evening. If the smoke chamber gets too warm, the bacteria you are trying to inhibit will thrive.

Decoupling Heat from Smoke
Your smoke source must sit in a separate tray or chamber connected by a vent. This ensures the combustion heat dissipates entirely before the smoke touches the food.
The method.
Prepare the fuel
Fill your pellet maze or tube with dry wood dust. Pack it firmly to ensure an even, slow burn.
Ignite
Use a butane torch to light the end of the dust trail until you see a steady orange glow. Let it burn for two minutes, then blow out the flame.
Stage the chamber
Place the smoke generator on the opposite side of the intake vents. Ensure your food is elevated on a rack to allow smoke to circulate underneath.
Monitor the draft
Keep vents mostly closed. You want a thin, consistent trail of blue-white smoke, not a heavy, billowing grey cloud that leaves an acrid, soot-like residue.
Rest
Remove the food after the desired time and wrap it in parchment paper. Let it sit in the refrigerator for 24 hours to allow the smoke flavor to mellow and distribute.
Other turns to take.
Hardwood Smoke
Hickory or mesquite for bolder, sharper flavors on fatty fish or aged cheeses.
Fruitwood Smoke
Apple or cherry for a subtle, sweeter finish suitable for delicate items like salmon or nuts.
When it doesn't go to plan.
Never reuse wood dust that has been sitting in a humid environment; moisture prevents the steady, slow smolder required.
Place a bowl of ice inside the smoking chamber if the ambient temperature begins to climb.
Always cure your meat with salt or a brine before cold smoking to draw out surface moisture.

Can I use a standard charcoal grill for this?
Only if you can physically separate the fire box from the food rack by at least two feet or use a chimney pipe to cool the smoke before it reaches the food.
How do I know if it's too much smoke?
If the food turns dark brown or black within an hour, or if it tastes metallic and bitter, the smoke is too dense or too hot.
