Years ago I was working as a cook at the YMCA camp in Estes Park...I learnd to cook in southren Kansas. Had a man from NYC ask for a 3 minuite egg...took me 20 minutes to explain to him that I had NO idea how long to cook a '3 min egg' at that altitude....not sure he ever did ger it. Settled for 'over medium'.

Where we live, to get 'hard boiled egg's they have to be in the simmering water for at least 12 mins
