Serves 4
Start with the mash: Peel the potatoes and cut into large chunks. Put in a saucepan with salted cold water and bring to the boil. Cook for approximately 15 minutes until soft.
Meanwhile, prepare the sausages: melt the butter in a frying pan and fry the sausages for approximately 7 minutes, turning them halfway through.
After 7 minutes, add the wine to the sausages and cook for 2 minutes, then add the cream and the mustard, stirring and bringing the liquid to the boil. Cook for another 2 minutes. Cover to keep warm and set aside.
Finish the mash: drain the potatoes and put back in the saucepan. Mash the potatoes and gradually add the milk and the butter. Mash until you have a fine purée (adding more milk if needed), then adjust the seasoning with salt and pepper.
Put a generous spoonful of mash onto each plate, top with 2 sausages and mustard sauce.
