Preparation:

Put the potatoes in a large saucepan of water and bring to the boil. Cover, lower the heat and simmer for about 20 - 25 minutes, or until the potatoes are done. Drain and when cool, cut into 1/4" slices. In a small bowl, whisk together the ingredients for the dressing. In a large bowl, assemble the potatoes, onion, dill, gherkin and radishes. Pour the dressing over and toss gently to combine. Transfer the salad to a serving bowl and chill for 30 minutes before serving garnished with the dill sprigs.
