My hypothesis is that it is moister dripping from the inside of the dome of my ceramic along with any "flavor"/gunk that has accumulated on the inside of the dome. But not sure...
Anyone seen this before? Next cook I a going to give the dome a scrub down to see if that helps anything.
I get this sometimes if I don't power-wash to clean my upper racks. Even if they are in the cooker with no food, slight amounts of smoke, vapor, and such will adhere to the empty racks. Even though they appear perfectly clean they will drop similar spots. No changes in taste and no harmful deposits.
