Move over, beef: there’s a new burger in town. Plant-based meats are sizzling hot right now; in 2020 alone, the alternative meat industry saw a record $3.1 billion in investment, with 112 new plant-based brands launching in supermarkets. These juicy, savory, chewy fake burgers are a far cry from the dry, weird-tasting veggie patties of the past. In this episode, Gastropod co-hosts Nicole Twilley and Cynthia Graber visit the Impossible Foods labs to swig some of the animal-free molecule that makes their meatless meat bleed, try fungal food start-up Meati's prototype "chicken" cutlet, and speak to the scientists and historians who compare these new fake meats to their predecessors—and to real meat! Can a plant-based sausage roll be considered kosher or halal? Are plant-based meats actually better for you and for the environment? And how might a mysterious protein-powerhouse fungus named Rosita help feed the world?This episode was reported and produced by our friends at Gastropod.Featuring Aymann Ismail, Celeste Holz-Schietinger, Malte Rödl, Tyler Huggins, and Raychel Santo.SUPPORTOutside/In is made possible with listener support.
