After several unsuccessful attempts to make half-boiled eggs. I decided to get the egg timer.
The first time that I used this, the eggs turned out over-cooked with some strange chemical smell. Very disappointing. I wanted to return it but my husband insisted on keeping it as it was too much trouble to return a $5 item online.
It was sitting in the drawer for weeks, before I decided to give it another try. This time, the eggs turn out slightly undercooked but that weird smell no longer exist.
The third time, it works like a charm. Learning from my prior failures, I removed the eggs once the egg timer reaches the 3/4 mark between soft and medium. They turn out perfect and beautiful. There is no weird smell.
I guess this was this was a keeper after all.
If you are getting one, cook the gadget once in salt water to get rid of the chemical smell. Clean it completely after that and let it cool before using it again. Due to the difference in temperature between the egg and the timer, it best to experiment a few tries for the perfect time to cook the eggs. You can buy the timer online on Amazon for US$5.
