Pomegranate, the last time I made it, I think I used less chicken bone broth and cream than called for. (I didn't make it this year, so it's been awhile.) I tend to be a free-style type cook and I don't measure exactly a lot of the time. And, erhm, I think I added a little white wine when cooking the sauce, which tends to reduce any kind of sauce.
The next time you make it, experiment, now that you know what it's like when you follow the recipe. An easy way to thicken would be to add a little potato starch to the sauce, which shouldn't change the overall flavor. The arrowroot would work, too!
You make your choices, and you live with them. In the end, you are those choices.
