I'm Trying to Dehydrate Marshmallows but they're chewy not crunchy
I'm dehydrating marshmallows in my oven as I don't have a dehydrator. I left them in the oven at 50°C for about 4 hours yesterday and then turned the oven off and kept them in the oven overnight (so they've been cooling in the oven for 11 hours now). They still aren't crunchy and have just become very very chewy. What can I do?
