Dehydrating carmelized onions ther right way?

They generally turn out “ok” for me, but I need some feedback on technique & final results.

I have a number of recipes. This one I used today Dehydrated Caramelized Onions (which utilizes the Instant Pot) is, for the most part, simple & sensible to me, but I have a few questions on details that may or may not be relevant.

  1. After removing the cooked onions from the IP, the chef, in prep for dehydration, squeezes much the liquid out of them. I understand that the goal is to shorten the dehydration process, but aren’t you also partially removing flavor as well ? All those sugars, or however you may want to refer to the caramelizing?

Any reason why I couldn’t/shouldn’t use the reserved onion broth instead of water in a second batch?

  1. One of my main frustrations with dehydrating onions is when I watch a chef showing the crisp final product. Mine never turn out like that. I can only describe them as, for lack of a better term, slightly leathery/bendy, not snappy crisp. What’s the trick? I can only relate it to time.

I’m always afraid that if I go too long, they’ll get hammered. I suppose there may be certain conditions under which time may vary somewhat, and must be considered. What would be a reasonable/dependable dehydration window guideline? What am I missing?

Why not test a small batch NOT squeezing the liquid out? I agree, might be lose some flavor.

As for why they don’t turn out crispy, my guess is they don’t dehydrate the onion but bake at a low temp, or higher temp for a short time but not sure. Squeezing the liquid out might help the crisping but again not sure. You could test a small batch as well.

I use a NESCO FD-80 Food Dehydrator. Always at 135F. The recipe calls for 125f-135f.

Any idea whether 125F might make a difference?
