Soak the pinhead oats in 2 cups of water overnight. Do not soak the oatmeal.
1 cup (170g) pinhead oats, 2 cups cold water
In the morning place the pinhead oats and soaking water in a heavy bottomed pan. Add the oatmeal and the additional cold water.
1 cup (150g) oatmeal, 4 cups cold water
Bring the porridge up to no more than 92 degrees celsius. Use a meat or jam thermometer to constantly measure the temperature. Do not boil it. The 92 degrees allows for the creamiest porridge possible.
Heat & stir with a spurtle for 20 minutes then add the salt. Add a little bit more water, depending on your desired consistency.
1.25 tsp Himalayan pink salt
Cook for a further 5 minutes and serve.
Notes
Cooking the porridge to 92 degrees celsius also works well just with oatmeal or even quick cook oats. In fact, it'll make for a creamy consistency with any starchy foods such as risotto.
