find a large stockpot with a tight fitting lid. Double line the bottom of the pan with tin foil. Add a handful of chips and cover with another layer of foil. Using an old deep fryer wire basket that has straight edges place upside down in your pot. If the handle prevents the basket from fitting inside the pot remove with wire cutters. Place the pot over the burner on high, after a few minutes gently lift the lid an inch. You should see wisps of smoke, signaling the chips are starting to burn. Put your food item inside, add lid and seal with extra foil.
Improvising a smoker like this will get very hot so reduce the smoke time by half. If smoking meats then finish the cooking process in the oven.
