I had to make scrambled eggs this morning for 40. I did it in my cuisinart skillet and put it into a ceramic dish for serving. I kept it in a warm oven for 10 minutes, loosely covered with foil, then wrapped in a towel. I got to the breakfast and 15 minutes later put it on a warming tray for another 20 minutes. The top layer was okay, but over the next 15 minutes I found the bottom inch getting quite green. I didn't realize you couldn't hold eggs that long. After googling, I realized my error. Oh well. I will cook them on site from now on!
