1, butter in a small bowl, heat until it melts.

2. Take a large container with a lid suitable for microwave oven (the lid must have air holes), put the rice in the container, then add the butter and white sugar, and mix well.

3. Cover the container, move it into the microwave oven and heat it at 900 watts (or high fire) for 4 minutes. Generally, the sound of "bang" begins to be heard in about 2 minutes, and it is almost the same when the sound of bang rings once every 2-3 seconds.

4. Take out the container, pour out the popcorn, and eat it after it is slightly cold.
