Koizumi Seiki has started selling "Egg Steamer" that can be made from hard-boiled eggs to hot spring eggs with a single switch. The price is open.
This is a convenient cooking utensil that allows you to easily make boiled eggs simply by adding water and setting a commercially available egg. Put the water measured with the attached measuring cup into the water pan of the main body, and set a commercially available egg on the egg stand. Close the lid and turn the switch to start cooking.
Hard-boiled eggs take about 16 minutes, soft-boiled eggs take about 10 minutes, and hot spring eggs take about 32-40 minutes. You can cook up to 6 hard-boiled and soft-boiled eggs and up to 3 hot spring eggs at a time. All you have to do is add water and set the eggs, so you don't have to boil a large amount of hot water in a pot or measure the time. Thank you for not occupying the stove!
Egg cooking lovers will find it useful when making oden, sandwiches, potato salad, curry, ramen toppings, etc.
