I don't half mess things up, that's for sure. I had it on a timer for six minutes (usually I just keep my eye on the clock, but eggs are unforgiving). I was also preheating the oven. When the timer expired, it beeps. When the oven reaches temp, it beeps.
It reached temp before the timer expired, but I heard the beep and thought, "Eggs are done!" Took them off, got them plated, then a couple of minutes later, the timer went off. Whoops!
I tossed them back in the water and simmered them for another minute, and I told MrsT, "These are either way undercooked or way overcooked." - and it was the latter.
Not too upset, because between the two, I'd rather have overcooked.
