When Microwaves first came out they were huge but with a tiny cooking area and they were not affordable, and were mostly in business kitchens and a few restaurants. I would love a freeze dryer but the cheapest I have seen is $1600 and they only have 4 small trays.
“Freeze drying is just freezer-burn to completion” was the line that really made me re-think how useful owning a freeze dryer would be.
