Carolyn and Smokin Soon,
I used to use Yoshidas teriyaki for my jerky all of the time. I used ground beef, Hi-Mtn seasonings ,and the jerky cannon. I was able to get my Yoshidas from Sam's Club here in Northern, NY for about $5 a quart. Sam's no longer carries it.
I don't have a Costcos here. Closest one is in Burlington, VT., and the cost of the ferry ride over would not be worth the trip. Any idea if Costcos ships, or where else I might be able to find Yoshidas?
