It seems to be useful when preparing condiments such as ginger and garlic. I found a product called "A grater with a lid" at Daiso, a 100-yen shop, and bought it.
A product that includes a grater, a container, and a lid. The bottom of the orange container is non-slip and does not need to be fixed by hand, so you can grate the ingredients with just one hand.
The point is that the container is made of a soft material. After removing the grate board, you can squeeze the water out of the grated ingredients by bending it from the left and right and tilting it. If this is the case, you can easily prepare ginger juice. There is also a special lid, so you can store the grated one as it is. However, the lid is not airtight, so be careful not to accidentally knock it down.
Since the diameter of the container is about 9 cm, it is suitable to grate small ingredients such as spices such as ginger and garlic. Also, since the "eyes" are fine, it may be better to use a different grater for ingredients that you want to grate roughly and enjoy the texture.
There is a limit to the ingredients that can be grated, but there are various convenient "graters with lids". For those who say, "I always use commercial products in tubes for condiments," why not give it a try? The price is, of course, 108 yen (tax included) per piece.
