There are many ways to make eggs become delicious; boil is one of the simple and common methods to cook eggs. However, one bad hard-boiled egg can ruin you for life. At least, that is what I believed until I learned how to cook soft-boiled and hard-boiled eggs precisely how I wanted to eat them.
The perfect hard-boiled egg has no green ring around the yolk and the innards are creamy and mellow. If you are in the mood, you can stop short of the hard-boiled and make a gooey soft-boiled egg instead. Hence, do you know how to make perfect boiled eggs? It is easy. All you need to care is the boiled time. Yes, you can use clock or your smart phone to control the egg-boiled time, but recently, I find an interesting egg timer which can perfect control the egg-boiled time and more convenient than other timers. With a cute egg-shape design, this timer is made of resin which is non-toxic and heat sensitive. It has three levels of boiled eggs: hard-boiled, medium-boiled and soft-boiled.
To let this stuff work accurate, do not immerse it in cold water with eggs at the very first. Wait until the water start boiling then immerse it into the water. After a while, you will see this timer is changing its colors to show you what situation the eggs are. With this interesting kitchen gadget, you can get perfect boiled eggs every time. However, if you use clock or smart phone as timer, the boiled time will take: 3 minutes for runny soft-boiled eggs (barely set white); 4 minutes for slightly runny soft-boiled eggs is; 6 minutes for custard yet firm soft-boiled eggs; 10 minutes for firm yet still creamy hard-boiled eggs; 15 minutes very firm hard-boiled eggs.
Since boiled time is the most important part of boiled eggs, once you control the time, eggs will be perfect and delicious.
