Marina, I used to do a lot of smoking, but haven't done any for such a long time. I attended a smoking demo at Hepburn Springs, way back. I was probably the best 'cooking class' i have ever been to. Many of Melb. top Chefs were there and all to learn from each other. They turned up with all type of smoking devices. The lady from the Avenel Hotel ,had an old fridge on a trailer strung with vegetables which she smoked on the spot. Someone else had built a cold smoker and another Dr from the Melb. Hospital had developed a method of smoking in a wood burning BBQ. He only used apple wood, which he dried for a year. Andrew O'Connell, now famous, (Golden Fields and Cumulus ) was there as a rising star. He and a friend had made sausages at home and had others smoke them. All food was available for sampling.
How I remember Andrew was that my daughter had shouted me to the event as a birthday pressie. She was also interested as she is a fly fisher and Andrew was trying to chat her up. It was a most extraordinary day. Sorry to ramble on but the vegetables were a class act so keep experimenting.
