I normally make mash with Maris Pipers and they do taste nicer than the bog standard white potatoes for all round uses. Tonight I decided to buy some Desiree spuds as the bag says perfect for mashing. They have a darker red skin. I peeled, washed, boiled, drained, mashed, buttered, milked and peppered in my usual way. Tasted great but I really can't tell the difference between them and the Pipers. Can anyone here discern between these, if you've ever tried both? Only difference I noticed is the Desirees were 20p cheaper.
