This course introduces a number of basic scientific principles underpinning the methodology of cooking, food preparation and the enjoyment of food. All topics covered have a strong basis in biology, chemistry, and physics application. Among others, they include the consumption of cooked food, the physiological and evolutionary implication of the senses, geographic and cultural influences on food, and the rationale behind food preparation. We will also discuss issues such as coupling of senses to improve sense stimulation; altering flavor by chemical means; and modification of the coloration to improve the appearance of dishes. Following the video demonstrations of the scientific principles of cooking, you will learn to recognize the key ingredients and their combinations for preparing good healthy food. At the end of this course, you will be able to:
- appreciate the scientific basis of various recipes;
- develop your own recipes by integrating some of the scientific principles into new dishes;
- recognize the influence of the material world on human perception from the different senses;
- appreciate the art of integrating science into cooking and dining.
Important Note: This course is not designed for people with special dietary needs such as vegetarian, diabetic, and gluten-free diets. If you feel uncomfortable with any part of the assignments or activities of this course, you can substitute some of the ingredients or ask friends and family members to help with the tasting of your assignments. Alternatively, you may skip that specific assignment provided that you have fulfilled all other qualifying requirement to pass the course.

Waiting for an extension to this course but at an advanced levelThis course is really valuable. It was presented in a simple and fun way I enjoyed studying with you thank you
If you enjoy cooking and also enjoy chemistry, this course is ideal. It taught me many techniques in the kitchen and why the food changes during the cooking process.
