If you don't care for this step, just transfer jerky to dehydrator set to 160F.
Pre-heat your oven to 350F.
Take out baking pans and line it with aluminum foil. Then put oven safe cooling racks on top of the pan so that the jerky is elevated. Elevating the jerky also helps prevent case hardening.
Arrange the jerky on the cooling racks so that they don't overlap.
Set a timer for 10 mins.
After 10 minutes, transfer to your dehydrator set to 120-130F.
