Pull the dough from the fridge. Dump it out to a floured surface and gently fold over itself a few times. Form a ball again, making sure it is well floured on the outsides of the ball. Cover and allow to rise and rest for 2 hours.
Preheat oven as high as it will go, mine is 525. Put the steel or stone on the rack about 3/4 high in the oven.
Prepare a pizza peel with flour and some cornmeal. Stretch the dough on the peel
Add the sauce to the pizza and spread it thin.
Add 1/4 of the cheese. Then add the corned beef and kimchi.
Add the rest of the cheese. Shake the peel to make sure the pizza is loose.
Transfer the pizza from the peel to the oven right onto the stone or steel.
Cook about 8 minutes until browned all around.
Remove from the oven, top with chives, slice, and serve.
