The typical water-to-rice ratio for cooking white rice in a rice cooker is 1:1. This means you should add an equal amount of water to the amount of rice you are using. Here's a simple step-by-step guide:
Measure the rice: Start by measuring the amount of white rice you want to cook. For example, if you are using 1 cup of white rice, you'll need 1 cup of water.
Rinse the rice (optional): It's a good practice to rinse the rice under cold water before cooking to remove excess starch. This step is optional but can help improve the texture of the cooked rice.
Add rice and water to the rice cooker: Place the rinsed rice into the rice cooker's inner pot. Then, add an equal amount of water. For 1 cup of white rice, add 1 cup of water.
Cook the rice: Put the inner pot into the rice cooker, close the lid, and turn on the rice cooker according to the manufacturer's instructions. The rice cooker will automatically cook the rice and switch to a "keep warm" mode once it's done.
Let it rest: After the rice cooker switches to "keep warm," allow the rice to rest for a few minutes before fluffing it with a fork.
Keep in mind that different rice cookers may have slight variations in cooking times and water absorption. If you find that the rice is too dry or too sticky, you can adjust the water amount slightly in your next batch until you achieve the desired consistency. With some experimentation, you'll get perfect white rice every time!
