Reduce hotness of beef Jerky
Jerky can be rehydrated.

Soak it in liquid, the way you would mushrooms, until it becomes somewhat plump. It will remain a little chewy and keep a lot of its flavor.

Chop it up and cook it into a stew. It will give a unique flavor and texture and the stew will dilute the spiciness- hopefully to a manageable level.

Look for recipes for "backpacker's stew" for examples.
