Everyone has their own way and opinions on how to hard boil an egg. My eggs always come out perfect even at a higher elevation. Here is how I do it. Place the eggs in a large pot and cover with cold water. Bring the pot to a boil and reduce heat to a medium temperature. Cook for 12 minutes (at 5600 feet), add another minute for every 1000 feet in elevation gain, reduce cooking time to 8-10 minutes at lower elevations. Drain the hot water and cover with cold water until the eggs are cool enough to handle. I like to peel the eggs when they are still warm, it seems to come off better. :)
