- Wash the rice and place it in a pot with the 1 liter of water.
- Cook the rice on medium heat until the grains soften and absorb the water. Be careful not to burn the rice by keeping the heat moderate.
- Add the 1 liter of cold milk to the pot. Stir once or twice and wait for it to come to a boil.
- Meanwhile, in a bowl, mix the rice flour with 1 cup of cold milk, making sure there are no lumps.
- Take 1 or 2 ladles of hot milk from the pot and slowly add it to the rice flour mixture to warm it up.
- Pour the rice flour mixture back into the pot and cook for about 10 minutes on low heat, stirring occasionally.
