At EAA AirVenture and a friend came over to cook WAGYU Beef Bavette steaks he gets from his local butcher. We cut them in half so they were about 8 inch x 4 inch and smoked them in the Ninja until 110 (he intended for 100) and then we seared them on the propane grill to bring them to 120 or 130, can't remember, and rest for 10'ish minutes. We use oak pellets.
I have not EVER NEVER EVER had a steak this tender and the flavor was amazing. This was by far the best steak I've ever had in my life. I thought I was at a restaurant commoners like me don't go to that makes steaks like this, ohh, it was my RV! OMGEEEEEE!!!!
