The amount of rice that can be cooked in a 1-liter rice cooker can vary depending on the type of rice and the desired consistency. As a general guideline, a 1-liter rice cooker can typically cook around 3 to 4 cups of uncooked rice. However, it's important to consult the specific instructions and capacity guidelines provided by the manufacturer of your rice cooker, as different models may have slightly different capacities and cooking recommendations. Additionally, factors such as the type of rice (e.g., long-grain, short-grain, basmati) and the desired level of fluffiness can also affect the final yield.
