If you do try making these or something similar, be careful on order of miixing. I did the seeds, oats anf water+coconut oil first, then the parsnip after it was doughy. If you put the parsnip in first you'll get clumps of shitty dough
My oven has a 'super convection' dehydration setting that i used at 150F for 6 hours to make mine. Any oven should work fine for them, but you may need to flip/rotate a few times depending on airflow. Baking them on parchment paper is helpful, preferably without being om a solid pan. They were extremely easy for me to flip after 3 hours, they should be fairly hard by then. If not, then probably more flipping and rotating is necessary.
Those do sound good. I'm needed a crispy snack recipe that's low on cholesterol and starch for Peter and these seem to fit the bill. Being dippable was critical :-)
