I'm so pleased you noticed the potatoes .... that is really astute of you as believe they are the star ....

I steam peeled charlotte potatos until soft. I let the steam evaporate off. I then add a rediculous amount of butter ie nearly a pack with some milk and an over the top amount of grated mature cheddar and mash it. I then bake it in the oven. This further intensifies taste. When the top starts to catch, I mix it so the whole dish has caramelised bits all the way through and carry on baking. I normally make two portions at the same time and use the second dish in a day or two. My favourite use for the second dish is to take some really good sausages eg red onion pork or something else with character. I skin the sausages and cut them into small bits say each sausage into 6, roll them into small balls, fry them, mix them with the cheesy potato and rebake.

To me the potato is the star.
