Sumac! No, I’m not talking about the wild stuff growing in your backyard that once gave you an itchy rash. While it is related, the sumac I’m talking about is far from poisonous, and makes a wonderfully delicious addition to any spice cupboard. Taste: Sour Most Popular Use: Spice blends, dry rubs, salads The sumac bush, native to the Middle East, produces deep red berries, which are dried and ground into coarse powder.
