You boil up some cut-up carrots and swede for 12 minutes, add cut-up turnip for another five, season, drain (keeping some of the water) and mash the mixture very roughly. If it's too dry, stir in a bit of the reserved water. It wants to be slightly sloppy but not at all runny. I tell you, it's delicious. And very good for you. Never diss what you haven't tried. You can even freeze it.
