Thanks for the pic. So let me see if I've understood your original thought & post.
Here it is while I was testing it "in controlled environment"
The "grill pan" you reference is sitting on the portable stove in your pic? Looks like its about 20 (+ or -) in diameter... or in US about 8 inches. And you also have a frying or boiling "basket" in the foreground of the pic full of potatoes cut into "chips" or "fries"?
Did the basket also come wih the wok?
