Rinse 400g of rice and soak with water for two hours.

After soaking, drain the water and place the soaked rice in a blender.

Add 150ml of warm water to the blender and blend the rice two times. Depending on your blender's model, blend the rice on fruit, smoothie, or high settings. It should be able to make a smooth batter similar to a pancake batter.

Once you have a smooth batter of blended rice, transfer it to a mixing bowl.

Mix in yeast, sugar, and all-purpose flour. Be sure to mix well.

Cover the bowl with a clean wrap and let the mixture double its size. When it doubles, you will also notice bubbles in the mixture.

After fermenting, stir the mixture once more and transfer it into cupcake molds.I recommend pouring the mixture into the mold's center and allowing it to flatten. Make sure not to overfill the mold to give it enough room to rise. You can brush the molds with a thin layer of oil to make unmolding easier.

Add raisins on top of each cup if desired.

Place the cups in the steamer and start steaming in cold water.

Once the water boils, steam for 35 minutes. Do not open the steamer while steaming since this will let heat escape and disrupt the rising process. Remember, the steaming time may be longer if you use larger cupcake molds.

After 35 minutes, turn off the heat and let it rest for an additional 5 minutes without opening the lid.
