Rice bubbles are made through a process of steaming, flavoring, and puffing rice grains.
Here's a breakdown of the process:
-
Steaming: Rice grains are first steamed until they are cooked and soft. This step prepares the rice for further processing.
-
Flavoring: Sugar, salt, vitamins, and minerals are added to the cooked rice. This enhances the taste and nutritional value of the final product.
-
Rolling and Shaping: The flavored rice then passes through large rolling pins or similar equipment. This flattens and shapes the rice into a more uniform consistency and size.
-
Puffing: Finally, the rice is subjected to a hot oven (or other heating method). The high heat causes the moisture inside the rice grains to turn into steam, which rapidly expands and puffs up the rice into the familiar "bubble" shape.
In summary, the process involves cooking, flavoring, shaping, and then quickly expanding the rice to create a light and airy texture.
