New Medium Green Egg. Cooked for first time lastnight. Cooked Salmon(in pan) for about 30 minutes @300. Salmon was thick steaks and took a little longer to cook. Afterwards I placed 3 large Onions in foil to cook @300. I went to check the temp about 30 inutes later and it had droped to 250. I opened top and bottom up and came back to check temp about 10 minuted later. Still @ 250. Swung Daisy top to the side(full open stack) and opened bottom all the way. 10 more minutes still @250. Coals still glowing and I notied some unburt coal on the edges. Used long rod and nudged the good coals from the edges toward the center hot coals. Still wide open top & bottom. 10 minutes later still 250. Alltogether almost 3 hours total time from start to when I removed the onions(time includes warmup and cooking of Salmon). How will I be able to smoke anything like this. Why would temp not increase. Still had unburt coals left.
