how do you make jerky in a gas grill?

Jerky used by the pioneers was simply meat "pulled" from the muscle rather than cut, then soaked in brine (saturated salt water) and sun dried by hanging the strips over a clothes line or wire.

Really

the pioneers were required to present the receipts for a years supplies of staple items before joining any wagon train

as for the Chuck Wagon, I am sure the every day spices were used even the ones for turkey and pumpkin pie.

how long is 20 miles a day for 3000 miles close to 6 months

and jerky was more likely an item that was made in the towns Rather than in the field It takes days to dry the meat

and they have a time schedual

But i guess a clever cook could keep the flys off the hanging raw meat within the covered chuck wagon.
