Fill two charcoal chimneys full of lump charcoal and place on the charcoal grate of the Yoder smokers Adjustable Charcoal Grill. Light the chimneys. When the charcoal is burning hot all the way to the top of the chimneys, dump into one half of the charcoal grate. Close the lid.


While the charcoal heats up, Soak the kitchen towel and about 5-6 feet kitchen twine in the red wine.


Lay out the wine soaked towel on a work surface that won’t easily stain. Spread the kosher salt over the towel forming an even layer large enough to cover the entire tenderloin. Spread the Cattleman’s Grill Road House Steak & Beef Seasoning over the top of the salt. Lay the tenderloin on the seasoning. Roll it around to coat the tenderloin. Wrap the salt and towel around the tenderloin, fully encasing it.


Tie the wine soaked kitchen twine around the tenderloin, trussing every 1”-1.5”. Pour extra wine on the cloth to fully soak.


Place the wrapped tenderloin directly on the hot coals.
