Sumac is a tangy spice commonly used in Mediterranean cuisine. It is made by drying and grinding sumac berries. Tart in flavor, sumac gives a rich reddish tinge to curries! I add it to salads. Found in Mediterranean grocery stores in California.

Health benefits: Sumac is rich in antioxidants (like many other berries). However, as of Dec 2020, not much written by Dr Greger specifically about these berries.
