This is how we make our basic oatmeal in the morning before customization and creativity take place.
Put oats and water into pot (we use a 2 1/2 quart pot) and bring to a rapid boil.
Reduce heat to medium boil and cook for 4 minutes, stirring occasionally.
Remove from heat and let stand for ~ 1 minute before serving.
If in hurry, add ice cubes and stir to cool the temperature down fast. This is what our kids do if they don't have time to wait for their bowls to cool to a comfortable temperature before school. Fitting for adults in a hurry who don't want to burn their mouths too!
