Where can I find pomegranate molasses and is there any substitute you would recommend if I can't locate it?

Thank you very much!

You can also use date honey with a squeeze of lemon juice.

Can you reduce fresh pomegranate juice to a syrup consistency and achieve the same flavors?

If you have a Middle Eastern market near you they'll definitely have it. You can also try a specialty grocery store, and Amazon sells it (pricey to ship, but delicious, and you don't need much in dishes so it lasts a while).

Absent that, I'd suggest tamarind paste/sauce - as it also has a similar consistency and tart quality.
