Add oats, water, raisins, salt and cinnamon into your Hamilton Beach Rice and Hot Cereal Cooker.
Program 'Delay Time' on your machine for at least 6 hours or overnight and set it to HEAT/SIMMER for 5 minutes. OR you can make the oatmeal immediately by skipping the 'Delay Time' and just go straight to HEAT/SIMMER for 5 minutes.
