So.... a couple of cooks in and I am very impressed ! And for £79 (plus some accessories) it is amazing. And no issues with quality or ease of construction.
Firstly, the Big Green Egg "plate setter" for the Mini fits very well. With the supplied grate sat on the "legs" it sits just above the rim.
With the plate setter in it will sit at low and slow temperatures for a remarkably long time. These ribs were about 6 hours. And I had enough charcoal left for the baby chickens below. Just gave them a rake and lit it up again. Due to the small size it heats up really quickly, and if you used a gas gun it would be even quicker.
These beef short ribs were very good and really held temperature well at about 110C for a long time with very little fiddling. About quarter of an inch open on the bottom and half a hole on the top.
For the price it is hard to complain however some things to note....
Three ribs or two poussin are about the limit. It is small of course
Very little space between place setter and grill so a water pan / drip tray has to be very short
You do need to stand it on a table or something
With indirect heat I found it difficult to get past 120C. Perfect to low and slow, but the chickens needed finishing on the gas. I think it is maybe that the airflow in the hole in the fire thing (cup, box, bowl ?) was restricted by too much charcoal.
The Big Green Egg cast iron searing grate will fit this. Although is almost as expensive as the egg itself for some pretty grill marks.
An ash removal tool is helpful, as you can just rake the coals, scrape some out of the bottom slot, and you are good to go.
