What Are the Tiny Bumps on the Rice Paddle in a Rice Cooker For?

Have you ever noticed that every rice cooker usually comes with a complimentary rice paddle? And if you look closely, you'll see that the surface of that paddle is often covered with tiny raised dots. So, what exactly are those tiny bumps for?

1. Non-Stick Function

The small, round bumps on the paddle help prevent rice from sticking to the paddle. They create just enough friction to hold the rice without making it cling, which makes scooping and serving much easier. Plus, it helps keep your rice cooker cleaner by reducing the amount of rice that sticks to the sides of the pot.

2. Protects the Rice Cooker’s Non-Stick Surface

Beyond preventing rice from sticking, these bumps also help protect the inner pot of your rice cooker.

For example, when removing leftover cold rice stuck to the pot before cooking a fresh batch, scraping with a regular spoon can damage the non-stick coating.
But with a textured paddle, those small bumps provide a gentle abrasion that can loosen stuck rice without scratching the surface — preserving the longevity of your rice cooker.

3. Helps Fluff Rice

The bumps also play a role in making rice light and fluffy. As you scoop and stir, they help separate the grains, reducing clumping and making your rice more airy and appetizing.

4. Easier to Clean

The design also makes the paddle easier to clean. Thanks to the textured surface, rice doesn't cling as stubbornly, and a quick rinse under water is often enough to get it spotless again.

How to Cook Fluffy, Fragrant Rice

Cooking rice may seem simple, but getting that perfectly fluffy, slightly sticky, but not mushy bowl of rice is a bit of an art. Here are some pro tips:

Choose Good-Quality Rice

Start with high-quality rice. Always buy from trusted sources and prioritize fresh, seasonal rice. Old rice can lose its natural sweetness and be more susceptible to pests and nutrient loss.

Look for grains that are uniform in size and color, not broken or discolored. A good variety will have a natural aroma without any musty or off smells.

Wash the Rice Gently

Even though most rice nowadays is pre-cleaned, a gentle rinse is still recommended to remove impurities.
Avoid over-washing or scrubbing too hard, as the outer layer contains essential B vitamins (B1, B2, B6), which can be lost with excessive washing.

Just swirl the rice gently and pour off the cloudy water — once or twice is usually enough.

Use the Right Water Ratio

This step is crucial. A traditional tip: touch the rice surface with your fingertip, and the water should reach the first joint of your index finger.
Alternatively, you can place your palm lightly on the rice, and if the water just covers your hand, it’s usually just right.
Avoid pushing your hand deep or pressing down.

Let It Rest After Cooking

Once the rice is done, open the lid and fluff the rice gently to let excess steam escape.
Then close the lid and let the rice sit for about 10 minutes. This final step helps the rice settle, allowing each grain to become soft, aromatic, and perfectly cooked — not soggy or dry.

These little details — from the bumps on your rice paddle to how you measure water — all come together to make a perfect bowl of rice, the heart of every home-cooked meal.
