First time grilling on my Yoder Smoker YS640. I purchased a set of GrillGrates but admit I was a bit sceptical as to whether the YS640 could really fire it up and grill like a proper grill. Well, I have to say, I was very impressed this evening. I turned the temp up to 500* and let her heat up with GrillGrates in place. I cut a chicken breast in half and seasoned with cayenne powder and southwest chipotle seasoning. The smoker was putting out a flame like my corn stove did back in Michigan. It did not take long for the heat to build up. I greased the GrillGrates with some oil and put the chicken on. It sizzled like it should. After a few minutes I flipped the pieces and finished cooking. This was just the second meal cooked on the grill, but very happy with the agility of it to go low and slow or fire things up for some hot cooking. I am including pics of the process, sorry for the low quality photos, time for a new camera. Capta1n Grill set to 500* Hard to see, but the flames were kicking. Seasoned chicken and oil for the GrillGrates. Chicken on, ready to season the other side. Nice sear marks on the meat. Cut up on the board. Cajun Chicken Pasta with tomatoes and green onion.
