Pour the milk into a non-stick saucepan and bring it to a simmer - small bubbles should appear on the surface. Don't boil the milk or it will burn
Slowly add the oats, salt and sugar stirring vigorously with a wooden spoon all the time.
Keep stirring until bubbles appear again. Then reduce the heat, cover the pan and cook gently for 8-10 minutes, stirring frequently. Cooking time depends on the thickness of the oats: the finer they are the quicker they'll cook.
When the porridge is done, it will be thick but pourable and the oats will be soft
Now add in some cream to taste and stir. You might also wish to add a table spoon of honey.
