Get out a medium saucepan, soup pan or Dutch oven and pour in the 4 cups water.Turn the heat to high and bring the water to a rapid boil.When the water comes to a full boil, pour in the steel cut oats and salt.Stir and let the oats cook for 1 minute. I always set my timer here. If your oats start bubbling and rising up, then just give them a quick stir and that should take care of it, but if they still keep rising up, then turn down the heat a bit. .After one minute, turn off the heat, give the oats a quick stir, cover and then let them sit out overnight.In the morning uncover the oats and turn the heat onto medium.Stir occasionally until the oats are heated through. There will be a bit of water in the mixture still, but the oats will thicken up as they sit. I really like this consistency because they're not to thick, goopy or dry.Ladle the oats into a bowl and top with your favorite fixings. I usually stir in a bit of dark or light brown sugar, add in whatever fresh fruit is in season, and then throw in some toasted walnuts and goji berries. You can really throw in just about anything.Store the leftovers in a sealed container in the fridge. The leftover oats will last for up to a week.To re-heat the leftovers, just put the cereal in a sauce pan, over medium-low heat. The cereal will thicken as it sits in the fridge, so you'll want to add a bit of water or milk to thin it up as it’s cooking.
