This is proper porridge, not your quick cook stuff.
Put the oats into a small pan with the liquid and slowly bring to the boil.
Turn the heat right down, then cook, stirring most of the time (stirring makes a creamier porridge) for 25 minutes.
You might want to add more water or milk as you go along, depending on how thick you like it.
Add sugar to taste – remember that if you're topping is sweet you don't want to add too much. Stir in the double cream.
Put into bowls and scatter the pistachios on top.
Serve with a topping of your choice, or try my recipe for port-baked fruit (pictured above) for a luxurious breakfast.
