Lily and Avery follow their noses to find out what gives foods their amazing aromas. Avery enjoys a super garlicky Caesar salad, then tries to sniff out a cure for his ghastly garlic breath. Lily makes a splash at the fish market where she gets to the bottom of seafood's suspicious smells. Together, they take on the ultimate olfactory challenge: recreating Matt's Amazing Seafood Chowder, by sense of smell alone.
