Summary

For a throwback, we’re looking back at one of our all-time favorite episodes—our science episode from 2020. We chat with flavor chemist Dr. Arielle Johnson about how to eat a tree, how insects use flavor molecules to communicate and the science of taste and smell. Plus, Meathead teaches us how to grill perfect steaks; J. Kenji López-Alt investigates food expiration dates; and we make a no-fuss, all-flavor Spanish Almond Cake.
