Cooking Rice

Figure 3: Simple steps for cooking rice.
- Using the provided measuring cup, add the desired amount of rice to the inner pot.
- Rinse rice under cool water until the water runs clear. This helps remove excess starch.
- For white rice, refer to the "White Rice Chart" below for recommended water levels. For other grains, follow specific recipe instructions.
- Place the inner pot into the rice cooker body and cover with the glass lid.
- Plug the power cord into a 120V AC electrical outlet.
- Press the cooking switch down. The 'Cook' indicator light will illuminate.
- Once cooking is complete, the switch will automatically flip up and the 'Warm' indicator light will illuminate.
