Yum! I love to cook steaks sous vide. I currently don't own a Kamado (yet), so I've had to improvise when it comes to the sear. Have you seen the Searzall before? I bought one a few weeks ago and love it. It's an attachment that goes on the end of a Bernzomatic TS8000 torch that turns the intense blue flame into a wider infrared burner. Since it's hand held, you can evenly brown all sides of the meat, especially the more oval cuts like a tri-tip. The biggest advantage over a hot skillet or grill is the intense heat (several thousand degrees). Only the very surface is browned. You won't get that thin layer of gray overcooked meat. And since the fuel is fully burned in the housing, the torch taste is eliminated. I am in no way affiliated with the company, just a happy customer.
