perfect soft boiled eggs

"When I want a soft boiled egg I want the yolk soft and the white firm. The boiling time has a lot to do with your elevation. 5 minutes is perfect for an elevation of 1100 ft (330 meters) if you are nearer sea level decrease the boiling time if at a higher elevation increase the time. I was surprised that there wasn't a recipe for soft boiled eggs posted (just one with saltine crackers) So simple as it may be I am sure there are many that struggle for the perfect boiled egg. Invest in an egg pricker, a little tool that will prick a small hole in the bottom of the egg allowing the air to escape, preventing the egg from cracking as it boils"
