I have recently been looking to make some nut butters and one of the main things everyone talks about is soaking the nuts then dehydrating them.
After googling all I can find out about is using the oven at about 150 degrees for 12 hours (maybe longer), or using a dehydrator.
I was wondering if there was a way to just leave them out for a period but that apparently causes internal mould to build up which is not good, and another alternative was possibly putting them in tin foil and putting them in a slow cooker. I would like to try the slow cooker approach as it seems a lot less cost but I have only found one instance of someone doing that and didnt really list their results.
So what is the most cost effective way to achieve the dehydration at home?
(p.s I am not mass producing I just thing its a waste of money leaving the oven on for 12 hours for a pot or two of nut butter)
