I love love boiled eggs. After several batches of edible, but less-than-perfect eggs, I was reminded of a nifty gadget my mom used to keep around. This little chunk of lucite reacts to heat the way eggs do, allowing you to cook a perfect hard-, medium- or soft-boiled egg. It works great, whether you subscribe to the “boil then add the eggs” method or if you prefer adding the eggs, then bringing the water to a boil.
