I found a kitchen utensil "Egg Driller" that says "Boiled eggs can be peeled off cleanly" with Daiso. I tried the usability.
Egg driller
"Egg hole punch" is an item for making holes in eggs before boiling. There is a small needle inside, and if you press the rounded egg firmly, a small hole will be created. Be careful when adjusting the grip strength so that you do not squeeze the egg when pressing it.
Now, boil the pierced egg as usual, soak it in cold water, and then peel it off. I was able to peel it off smoothly. However, it does not always come off cleanly, and it is a fact that the white meat may collapse. If you want to make sure you have a clean boiled egg, it's best to boil a lot.
The price (tax included) of Daiso's "Egg Driller" is 110 yen per piece. If you have many opportunities to make boiled eggs, why not give it a try? Please also check out the previously introduced " How to make a boiled egg that peels off " and " Peeling an egg shell".
