I have read on a few posts that eggs can be hard cooked in the oven. I tried it today..and after about 20 minutes, some of the eggs exploded. Fortunately, the eggs were already cook. Is there some way to stop the exploding part? I think I was cooking at around 360 degree. If I lower the temperature will this be less likely to happen? I really like the idea of not having to use water to cook the eggs.
