Sorry..what is Nar..sounds good if it can go in salads and soup
In Turkish it's called Nar Ekşisi and KKOB is right the best stuff is made by the villagers and found at the village markets. You will see it, a very dark brown colour in reused half litre water bottles and a little goes a long way.
It makes a nice and healthy dip mixed with olive oil and pepper flakes for dipping bread.
Anne the salad dressing is possibly a mix of the pomegranate sauce and olive oil with seasoning. We use the pomegranate sauce a lot in some of our mezes.
