Bees collect sap. They then reduce it by dehydrating it. Think about it... they fan it, to drive out the moisture.
That said, what if you got your syrup, however you get it... juicer, apple cider press, or just chopping and boiling the plant, any how, reduce it by boiling it a bit.
Then, when it begins to thicken and starts wanting to stick on the pan...
what if you cooled it a bit, then spread it in your dehydrator like a fruit roll up? Of course, with a moisture sheet, not the open holes!
That was my plan anyhow to get it thicker than just runny syrup, and dehydrate it. You could even build a solar dehydrator. I am not interested in bleaching the "sugar" but I would like to reduce it so that it no longer will support molds.
I have also researched getting sugar out of rice... yep plain white rice can be boiled into a syrup.
And let's not forget the tree saps, not just maple, that make great syrups.
