Did you ever get yourself a dehydrator or are you using the oven?
Deer jerky is pretty good as well. (softer)
One of those bags doesn't even cut 15min for me.
Ich bevorzuge Schinkenbeisser o.ä. Dried meat is against my personal views of healthy stuff. I have grown up with meat that has been refrigerated all the time to keep it in good condition. Does this taste more like leather or is it actually soft when chewing on it? What i also like from time to time are "Landjäger" which are also dried pretty much
