Got this great tip from Alan N from Hong Kong.
As discussed in another thread, grilling on the SJG can get disappointing as the heat dies when you put the lid on (poor airflow / design). Alan advises closing one side vent, stacking the coals on that side then using a simple piece of foil over the open vent to guide airflow under the coals (you keep the lid vent open and above the coals).
this is how it looked when set up
after 2 hours with lid on
This worked really well, I love grilling on the SJG, it's perfect for our family of 5.
The coals lasted long enough for some teriyaki chicken tenders
Then burgers after that
