Food52ers, I know you'll know! How do I find (where do I find) good sumac? (An online source would be ideal for me.) I bought some at a local grocery store recently and, while it's a pretty color, it has none of the bright tart flavor that sumac is known for.
Thanks so much!!
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
