John Thorne wrote about the 'world's greatest cookies' in one of his books—they were thin and crispy and filled with demerara sugar. They were tasty, but not the greatest for me or the folks I fed them to.
I'm curious what qualifies as the 'world's greatest cookies' to baking experts, as I expect I'll spend the month of December baking cookies.

Some of our baking experts have weighed in—what cookie would you say is the 'world's greatest'?
