In this Versus episode, it’s the battle of herbs and spices. Get your fill of these fascinating aromatic plants that have flavoured our food and changed our history since paleolithic times. Learn why they bother smelling so good—and what you can do to make the most of their flavour—then get ready to cast your vote in the Plant Face-Off. Sean is representing the herbs with bay laurel, a plant not to be confused with the many other bays and laurels in the world—especially not the toxic ones. Learn how it grows, how to preserve the leaves, and why there are so many misconceptions about its safety. Erin follows up with mustard seed and how to grow and prepare it…but first she shakes things up with some tasty knowledge about spices around the world.

Who won the Plant Face-Off? Was it Sean with bay leaves or Erin with mustard seed? You decide! Send your vote by email or on Instagram, TikTok, or Facebook with the hashtag #PAWFaceOff.
