Just need a little encouragement. First time using Egg, got my thermometer problem taken care of. According to the Recipe section for a 1/2 pound burger heat to 700 for 3 min then flip and turn vents off let cook 15 min for a medium burger. Is there any recommendation or change to this. I thought I read somewhere to go up to 500 and shut down does the temp have to be just right. A little nervous and excited don't want to to flop family has high expectations from me.
