I'm trying to figure out if my preservation skills are valuable (to others). Would you be willing to buy a pint of dehydrated diced apples for 21K sats +shipping?

It would not come with the pint jar. You can supply your own.
I kinda want to buy and dehydrate more apples, but we are already headed for being over budget this month for food. So unless I can earn some money in the process, I'll just buy & dry apples next year (because these sale prices aren't going to last forever).
