About this recipe: This is a vegetarian version of the traditional stew from Scotland with potatoes, Cheddar and fresh nettles. Be careful and wear gloves when you handle the nettles. They will lose their sting though, after boiling.
Mangle is a yellow-fleshed beetroot, with a milder flavour than the typical red variety. If you can't find mangle, don't substitute regular red beetroot; simply omit it from the recipe and you'll still have a wonderful dish!
