"White-haired green onion" used for toppings such as ramen and char siu bowl. "White-haired green onions" are indispensable for accenting the appearance and texture, but making them with a kitchen knife is a little troublesome, isn't it? The writer may also just substitute the sliced green onions ...
I found an item that might be useful in such a case at a 100-yen shop! It is a "leek cutter" that makes it easy to make gray onions. The price is 100 yen per piece (excluding tax).
■ How to use1. 1. Hold the side and remove the cap, and make a notch of the desired length on the surface of the green onion with a green onion cutter. Be careful not to cut your fingertips as the blade is sharp.
2. Make a notch all around the surface so that the blade does not reach the core of the green onion. At this time, if you slice the sliced surface so that it overlaps, the green onions may be cut in the middle, so be careful not to cut them in layers.
3. 3. Avoid the part where you started cutting and cut it off with a kitchen knife so that the green onions do not connect (it is recommended to remove the core part and use it for other dishes)
4. Lightly loosen and complete the gray onion! Soak it in water for about 5 minutes before topping it, and drain it thoroughly with kitchen paper.
A convenient "leek cutter" to have one. The sharpness is outstanding, so be careful when handling the blade.
