I'll kick off with some apple I'm doing today.
Standard bag of apples from the supermarket, lemon juice, corer.
Core and then slice the apples. Put them into apple juice and water, stops them going too brown.
Dry slightly ( use kitchen paper or tea towel) and arrange on tray from dehydrator.
This bag of apples filled 3 trays.
These should take about 9 hours. I'll add some more photos later.
I have made some before sprinkled with cinnamon which makes a nice change.
Apologies for the size of photo, taken with iPad!!!!

Finished product. Will be stored in a Kilner jar.
