Thanks for your response. I am hoping to just smoke mushrooms, salt and pepper. At the moment I am just thinking of doing this on a small scale- to sell at farmers markets and at my local deli's, then hopefully, if they sell well I can think about upscaling and trying to make a serious business out of it.
The polyscience smoking gun is just an injection of smoke I know- but if I experimented and added a few injections over a long drying period in a dehydrator I wonder if this would impart enough of a smokey flavour. Bearing in mind its veg and not meat, this might be something that could work.
I'm not looking to sell something that just looks smokey, I'm really keen to develop something that people will really enjoy- I've been eating smoked mushrooms for a long time but I've always prepared them by hot smoking. In order to extend the shelf life drying would be necessary, so I'm keen to see how I could combine the two processes.
I am not talking about buying a commercial smoker and hiring premises etc. It's not really the feel I'm going for and I don't have the money for that anyway. If I could just give the small scale operation a go, and gain some knowledge and experience then maybe a year or two down the line I can write a business plan and get a loan, but for now I'm just trying to find a way to do this domestically.
So basically I'm just chucking ideas about hoping to gain some guidance, which seems to be working!
