Overview

In this course, which investigates physical transformations in food, we will be visited by world-famous chefs who use a number of different styles and techniques in their cooking. Each chef will demonstrate how he or she prepares delicious and interesting creations, and we will explore how fundamental scientific principles make them possible.

Topics will include:

  • How cooking changes food texture
  • Making emulsions and foams
  • Phase changes in cooking

You will also have the opportunity to become an experimental scientist in your very own laboratory — your kitchen! By following along with the recipes of the week, taking precise measurements, and making skillful observations, you will learn to think like both a chef and a scientist. This practice will prepare you for the final project, when you will design and perform an experiment to analyze a recipe of your choice from a scientific perspective.

The lab is certainly one of the most unique components of this course — after all, in what other science course can you eat your experiments?

Syllabus

Module 1: Elasticity
How do we describe food texture? In the first module of the course, we will explore the scientific concept of elasticity, which influences the texture of food, and how it changes during cooking. Discussions with Bill Yosses and Mark Ladner will address the role of gluten in dough and the challenges of working with gluten-free varieties.

Module 2: Viscosity
How can we make liquid foods more appealing? Just as solid foods can have different textures, so can liquids, largely determined by their viscosity, or thickness. Scientific discussions about what determines viscosity and demonstrations of different ways to change the viscosities of foods will allow us to explore this topic from different perspectives. We will hear from Harvard’s own Martin Breslin, Director for Culinary Operations, and Carles Tejedor, from Oillab and By restaurant in Barcelona.

Module 3: Emulsions and Foams
Emulsions and foams are some of the most interesting foods to think about from a scientific perspective, and we will investigate the physical principles that control their formation. Nandu Jubany will demonstrate how he uses emulsions and foams for a twist on traditional Catalan cuisine at his restaurant, Can Jubany. In the lab you can compete with other learners to see whose emulsion and foam rises the highest!

Module 4: Advanced Phase Behavior
The preparation of chocolate and frozen desserts such as ice cream are great illustrations of how chefs manipulate phase changes such as crystallization (freezing). In this module, we will discuss such concepts as nucleation of crystals and freezing point depression, and see how they can be used for chocolate tempering and making ice cream, which you will make yourself in the lab!

Module 5: Enzymes
The activity of enzymes can provide both benefits and challenges in the kitchen. After discussing the diverse roles that enzymes can play, we will investigate strategies to both restrict and exploit enzyme activity in cooking. Ted Russin and Wylie Dufresne will showcase some of their creative dishes that are only possible because of enzymes.

Module 6: Baking
To conclude the course, we will see how many of the topics that we have discussed come together in a popular cooking technique – baking! Joanne Chang and Christina Tosi will show us how to make delicious cakes, cookies, pies, and bread, and we will see how science makes it possible!

by Kristina completed this course and found the course difficulty to be hard.
This course gives you the physics behind the cooking process. You'll learn about elasticity, viscosity, foams and emulsions, manipulating phase behavior, enzymes, and baking. You'll learn why we can mix oil and water, what makes meringue stiff, how come our pesto turns brown or apples, and ow to prevent that. You'll learn about enzymes and their activation, pressure and viscosity, manipulating phase behavior to stabilize food or to create entirely different food, and to see how the addition of sugar, salt or similar ingredients actually influences the physical behavior of your dishes. Lots of professional chefs are illustrating the issues and problems given in the lectures, and the lectures are nicely given, understandable, and fun. You have lots of practical work if you want to get graded, but it's fun to apply this knowledge in everyday practice. A huge recommendation!
