In my UDS I fill the basket nearly to desired level, then light it with a chimney of lit lump. I light the newspapers in the bottom of the chimney and let it burn till it's got white on the coals then I put on a welders glove and pour the coals on top of the basket. After that I wait for the temps to climb, and the smoke to go to a very light blue, kinda wispy... All before I add meat to the UDS. (Works for me)
