Gumb suggested making my questions into a general kamado accessories thread, so before I ask my actual questions I'll start by mentioning two accessories we already know a lot about.
Smokeware chimney cap for kamados (forum thread) - stainless steel replacement for the daisy wheel on most kamados. Can be fitted to all the major brands, ceramic and metal. Offers better control and doesn't let in the rain. Can be bought from Urban Griller and probably other places.
Tip top temp (forum thread) - daisy wheel alternative with a coil that expands/contracts with heat. That is, it opens/closes reactively to the outward airflow temp and that regulates the temperature. Can be adapted to most kamados. I think I explained that reasonably accurately (mine is on its way so I'm going by the videos). Can be bought from Urban Griller and maybe other places.
Now, accessories for my dragon kamado are nonexistent, so I'm looking for alternatives. I'm hoping some of you have suggestions.
1. A while back in one of the 'what are you cooking this month' threads, I saw a picture of some wings on a kamado, but it looked like the coals were ~10cm under the main grill grate. I'd like to do something along those lines because with the fire normally so far down, to sear I have to get it roaring and then if I open the lid it fairly quickly takes off and gets ridiculous. It also might be useful for charcoal chicken.
2. I'm not convinced about the cast iron grill. Sometimes it's good but I often find myself wishing I had a stainless one like the Joe's or basically every premium brand kamado. Once I'm allowed to visit shops again (Canberra, lockdowns, yay) I'm going to drop in to BBQs Galore and measure up some of the KJ parts and maybe I'll be lucky.
3. What's a good place to buy stainless, circular grills of different sizes?
