This is a tale of woe, and partial redemption.
For the extra $200, buy the large, not the medium. Why? Because almost all of the accessories that BGE sells for the large AND medium, do not fit the medium.
I started with the V-Rack. With the plate setter legs up, it does not fit when you try to close the lid. Then I got the Grill Extender. Again, with the plate setter legs up, the lid won't close. Even though both are clearly marked as being sized for the medium.
My dealer took back my V-Rack and gave me the one for the small, and that fits. I need to return my grill extender. My dealer said he will take it back, it's just a question of getting over there.
Thus far, the folks at BGE have not responded to my "unhappy-gram". It was not a nasty-gram.
I don't know what my options are regarding the grill extender. I think that I have any.
Then, this past Saturday I went to the Eggs By the Bay Eggfest, and I saw a demo on baking bread in the egg using a cast iron dutch oven. Down to Target I went and got a 5qt dutch oven. Without the lid on the dutch oven, I can close the lid on my egg, but with the lid on, it don't fit. So..... What to do?
I put a fire brick under my egg on day one, so I have the little green feet available. I removed the grill, put the little green feet on the plate setter, then the the pizza stone on the little green feet, then I put the dutch oven on top of the pizza stone. Now the lid on my egg closes.
Tomorrow, Tuesday, I cook bread. I will let you all know how it goes.
PS: Do the medium and the large share the same wood table?
