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?
This course focuses on the physical changes that occur during cooking. If you are interested in signing up for the companion course, which focuses more on chemistry in the kitchen you can do so here.
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!
MOOCs stand for Massive Open Online Courses. These arefree online courses from universities around the world (eg. StanfordHarvardMIT) offered to anyone with an internet connection.
How do I register?
To register for a course, click on "Go to Class" button on the course page. This will take you to the providers website where you can register for the course.
How do these MOOCs or free online courses work?
MOOCs are designed for an online audience, teaching primarily through short (5-20 min.) pre recorded video lectures, that you watch on weekly schedule when convenient for you. They also have student discussion forums, homework/assignments, and online quizzes or exams.
