We've had our cadac bbq which is gas for many years but we do miss the taste of bbq food done on charcoal.

We filled a smoker box with the apple wood chips which we had previously soaked in water for approx 20 mins
We then put the box on the bbq filled with the apple wood chips. We decided to grill some burgers and sausages then closed the lid. The smells coming from the cooking was wonderful.
Our taste test definitely found the flavour was much improved so we will continue to use it.
The downside was we had to keep the lid closed for it to work which was difficult to keep our eye on the food.
Hope my comments are helpful.

I've only just started smoking our BBQ meat. Done chicken, trout and a bit of ham. One and a half tablespoons is ample for half an hour cooking in my "Cameron stainless steel smoker" even in mid winter. I'm cooking on gas. I'd purchase these oak chips from this supplier again.

Excellent value for money, the apple wood imparts a really good golden colour to my drinks and a nice smokey flavour. There is not much scent from this but I bet if you soak it in alcohol it will impart more scent.
