Anyone knows what these bumps on a rice cooker spoon are used for…

The entire procedure is made simpler and more efficient by the water’s ability to release the rice from the pot and the scoop’s rough surface, which helps to pull the rice out more effectively.

In conclusion, a rice scoop’s tiny grains are intended to improve functionality by minimizing the quantity of rice that remains at the pot’s bottom and making cleanup easier. Making the most of each batch of rice you cook is made possible by this careful design element.
