This was very tasty, however the color didn't make it very appealing and the dressing was a little runny. Next time I would strain the yogurt using papertowels in the bottom of a collander and allowing it to drain for a couple of hours to thicken. But had a good overall flavor. I would also increase the amount of tarragon.
This was a simple potato salad . We didn't find the tarragon flavour strong enough. I did like the addition of walnuts
NIce presentation and my DH and I really enjoyed with supper. I did scale the recipe down for 2 people. Thanks and good luck!
