Cherry Burl
Turn it as either of the previous posts suggested. Burl is a bit more stable than regular wood in my experience. I leave wall thickness on the initial turning about 8-10% of the major diameter, or in your case there will probably be 3/4" thick by the time you get it round and shapely. Put it in a plastic bag, wait two days then take it out, turn the bag inside out and place the turning back inside. Repeat this until you put your hand inside the bag and feel no condensation. This means that the free water content has evaporated, usually for me in NC that will be a month to a month and a half. Skim cut it to true it up and open fresh pores. It will be OK to sit out in the atmosphere and dry for an additional few months (for me 4-5) so that the bound water evaporates. Then do your final turning. This process has worked for me on most any type of wood, burl or other, for many years. It takes a while but minimizes checks and cracks, creates a micro climate around your turning each time you flip the bag, and lets the wood slowly relieve it's stresses. OR... you could turn it green down to 1/8" and let it move however it wishes. They are kinda cool that way too. Good luck with it!
