The Stöckli dehydrator

This is the method I unreservedly recommend. I do not have shares in the company which produces this dehydrator nor do I get paid for saying that the Stöckli is the most reliable product I know. I set the temperature at 50 - 55 (Celsius) and the timer to 12 hrs. After that time the mushrooms should be crackle, crisp dry. If not, give it another couple of hours. You can stack upto ten trays. The link to Stöckli is here and you can also order it from a mail order shop in London. The link is here (www.mycologue.co.uk).
