5 stars with butter I'm sure. Since the recipe says to cut the potatoes into thick round slices you definitely should lightly fry the potatoes, this also gives more flavour to the dish. I did mine in olive oil as we are dairy free here. In place of the butter I used some grape seed oil and like Morti, after the rice is cooked I rim the pan with paper towels and put on a tight fitting lid. This was good without the butter but not as flavorful. I did add some sea salt at the end as I felt it needed it without the addition of butter. I may make this again with a dish that has a sauce to it.
One of my favorite way to make persian rice! I love those crisp potatoes. I always placed tea towel on top of the pot before putting the lid on to absorb some of the steam and the potatoes were crisper.
I have always been making this a wonderful recipe....only thing I do is lightly fry the potatoes. Whatever you do this dish turns out excellent. It can be had as it is or served with some fried chicken. Mine I serve with a chicken dish.
