Once you have them, you will not have a chance to buy more colanders and bowls, but it may be convenient to have them! Introducing the "Dustpan Zaru Bowl Set" sold at Nitori.
It is a set of a colander and a bowl with a diameter of about 15 cm, but it is characterized by being partially flat. The biggest point is that you can scoop up the finely chopped ingredients like dustpan by sticking this part to the cutting board.
It is smart to put the scooped ingredients into a pan or frying pan as they are. The bowl has a scale, and you can measure water and seasonings in the same bowl.
Furthermore, both are compatible with microwave ovens. Of course, it can also be used as an ordinary colander or bowl, and it seems that it can be widely used for preparing ingredients.
A ring for hanging storage is attached, but since it is self-supporting, it is easy to use even if it stands upright. The author, who has a colander and a bowl, wanted to keep this on the counter!
