Why Heat Makes Food Delicious: Browning, Charring and the Maillard Reaction | Cook the Science

Why does a sear make a steak taste incredible? Why does bread crust taste different from the soft inside? The answer is heat transfer — and the chemical reactions it triggers. In this first ever Cook the Science lecture, ETH Zurich professor Dr. Thomas Michaels joins celebrated Alpine chef Rebecca Clopath to explore the science of heat, browning, and flavour. From the Maillard reaction to caramelization, conduction, convection, and radiation — this lecture reveals why heat is the most important tool in cooking. What you'll learn: • The three types of heat transfer: conduction, convection, and radiation • What the Maillard reaction is and why it creates flavour and colour • The difference between Maillard browning and caramelization • Why charring adds complexity and when it becomes bitter • How to control heat to cook meat, vegetables, and fish perfectly Chapters: 0:00 Welcome & Introduction 2:00 Meet the Guest: Chef Rebecca Clopath 5:00 Why Heat Matters: A Cooking Physics Overview 10:00 The Three Types of Heat Transfer 18:00 Conduction: Pans, Temperatures and Searing 26:00 Convection: Ovens, Water and Steam 32:00 The Maillard Reaction: Browning and Flavour 42:00 Caramelization vs. Maillard: The Difference 48:00 Live Demo: Charring and Browning Vegetables 56:00 Low and Slow vs. High Heat: When to Use Each 1:05:00 Q&A Cook the Science is a free public lecture series at ETH Zurich, where leading scientists and top culinary experts reveal the hidden science behind cooking and food. 🌐 Website: https://www.ethz.ch/cookthescience 📸 Instagram:   / cookthescience.ethz   🔔 Subscribe for new lectures:    / @cookthescience
