Wash the potatoes and cut in halves. Put them into a saucepan with ½ teaspoon of salt and cover with water. Bring to the boil, then turn the heat down and simmer for 10 minutes or until you can prick them easily with a fork
Drain the potatoes and allow to cool slightly.
Wash and thinly slice the radishes. Wash and snip the chives or wash and finely slice the white part of the spring onions.
Mix the horseradish sauce with the crème fraîche. Add this to the warm potatoes along with the radishes and the chives or spring onions.
Mix well to coat all the ingredients and serve.
Recipe Notes
Quick and simple but the horseradish make it taste really special. Wholegrain mustard works well too if you don't have any horseradish.
