First of all, the reason why the rice didn't burst may be because you didn't use a suitable container or there was not enough water in the furnace. When making popcorn, it is necessary to use suitable containers and add enough water to ensure that the rice grains are fully heated, expanded and exploded. The best choice is to buy a microwave oven bag specially used for making popcorn, so as to ensure that every popcorn can be completely popped and avoid burning or scorching.
Secondly, the temperature in the furnace is also one of the factors that affect whether the rice grains can be fully exploded. If the power of your microwave oven is low, you may need to increase the baking time or put the rice grains in the center of the microwave oven. If your microwave oven has a high power, you can reduce the baking time appropriately, or put rice grains on the edge of the microwave oven to avoid overheating and burning.
There are also some tips to help you make popcorn more perfect. During the baking process, you can try to constantly observe the situation in the oven and pay attention to keeping the microwave oven dry, so as to avoid the water vapor affecting the quality of popcorn. If you find that some rice has been cooked, you can stop the machine immediately and take out the finished popcorn to avoid overcooking or burning.
In a word, the skills and methods of making popcorn need to be tried and explored constantly. If at first you don't succeed, don't be discouraged. Try many times and gradually adjust the baking time and method. I believe you will get the best result.
