New Potato Salad

Directions

1. Wash the potatoes and cook in boiling water until just tender. Chop the green onions and dill. Drain the potatoes in a colander and run cold water over them.
2. Cut the potatoes into quarters or halves as soon as they can be handled. Place the potatoes in a large mixing bowl. Add the peas to the potatoes.
3. To prepare the dressing: place the white wine vinegar, Dijon mustard, salt, and pepper in a blender of a food processor and blend until combined (about 5 seconds).
4. With the motor of the food processor running, pour the oil in a slow, steady stream until incorporated. Pour dressing over potatoes, add the onion-dill mixture and toss gently.
5. Fold in the sour cream. Let the potato salad stand for 30 minutes before serving.
