Hardcore Carnivore Black: Activated Charcoal Meat Seasoning Rub (13 oz Shaker) Texas-Made, Blend for Steak, Brisket, Burgers, BBQ, Grilling and Smoking

Hard core carnivore https://a.co/d/099pkRnv and like you said coarse ground black pepper / salt

Came across HardCore Carnivore black tonight. They add activated charcoal to salt & pepper to create a blackened crust without burning. Definitely dump the foil, I don't wrap anything on the smoker anymore. If you do feel the need to protect it go with butcher paper. Foil is for the rest only. https://a.co/d/0bl23D6w
