Many herbs come from the backyard garden. But there is a whole world of tastes to explore. Donna takes us through the familiar and not so familiar world of herbs and spices.   In this episode, Donna and Lonna discuss lemon grass, black lime, star anise, bayleaf, hyssop thyme, sumac powder, and a wide variety of peppers.   Guest Ben Hoksch, Iowa naturalist and forager, introduces us to the surprising taste of Prickly Ash berries. (Quite an adventure for the taste buds.) Lonna gives a short lesson on saving tomato seeds.
