One cup long cooking oats (instant oats are nutritional crap), two cups COLD water. Either cook for two minutes in microwave, stir and cook again one more minute... Or, bring to a boil on stove top, turn heat down to simmer for about four minutes... No matter how you cook it, then cover, remove from heat and allow to sit at least ten, better five minutes, stir to distribute remaining heat. Add sugar, nut butter, or pro, stir again to blend. Serve when you can put a bare, clean finger into the porridge and leave it there without pain. I serve on paper plates as a foraging food and may or may not add fruit, nuts, etc.
