HIC Kitchen’s Perfect Egg with color-changing indicator visibly shows when eggs are perfectly cooked for soft, medium, and hard-boiled, without underdone or overdone yolks. Unlike traditional hourglass or mechanical timers, Perfect Egg uses heat rather than time to sense when eggs are cooked. The unique color-changing indicator heats up in the water at the same time as the eggs. Its gradient scale changes from red to white while eggs cook to visibly show when eggs are cooked to perfection. There’s no mechanical gadget to set or guessing how long to boil eggs. Simply add Perfect Egg in with the cooking water and eggs before heating the water, then cook until the color sensor matches the desired doneness. It’s ideal for perfect soft-boiled dippy eggs for topping avocado toast or dunking buttered toast soldier strips, and medium to hard-boiled eggs for deviled eggs, egg salad, pickled eggs, potato egg salad, lasagna, soup, and ramen. Cooking times range between 10 to 18 minutes. Made from BPA-free polyresin with a heat-sensitive color-changing indicator, HIC Kitchen’s Perfect Egg is sturdy, durable, reusable, heat safe to 212-degrees Fahrenheit, and hand washable. Allow it to cool completely before handling.
