Perfect Soft Boiled Eggs

For years I've been in search of the perfect soft boiled egg. This year, I've studied the matter and come up with this:

1. boil some water in a pot, enough to cover the eggs. Don't add the eggs until the water is boiling;
2. warm the eggs first, a glass with warm water will work fine. This keeps them from breaking open;
3. add the eggs to the boiling water, leave the pot uncovered, boil for approximately five minutes. Use a timer;
4. when time is up, immediately cool eggs under running cold water from your kitchen tap for five to ten seconds (this stops them from cooking);
5. break open and add to serving bowl. Hopefully, they're perfect. If not try again and vary the time.
