Okay so homemade mashed potato is lush, but why not save yourself 30 mins of washing, peeling, boiling and mashing and buy it instead, especially if it's for on top of a pie! Now I buy the mash (from the co-op down the road!) and add it to any pie from fish to cottage and nobody is any the wiser! I checked the ingredients and there are no hidden nasties in there - usually just mash, butter, seasoning and milk. (Tips: warm up the mash in the microwave for a short time, makes it easier to spread and add horseradish to jazz it up a bit!)
