Place the oats and the milk or water in a large pan over a medium heat. Add a tiny pinch of sea salt and stir with a wooden spoon. Bring to a steady simmer for 5 to 6 minutes, stirring as often as you can to give you a smooth creamy porridge – if you like your porridge runnier, simply add a splash more milk or water until you’ve got the consistency you like. Jazz up your porridge with your favourite combo of fresh fruit, nuts and seeds, sweetening to taste – see below for inspiration.
