The chemistry of cooking
I love cooking and want to know why recipes work: what heat does to proteins and sugars, why salt, acid and fat matter, how emulsions and doughs form, and how to fix things when they go wrong.
What you'll learn
14 chapters
- 1
Cooking as Chemistry: What Changes in the Kitchen
- Define cooking as a set of physical and chemical changes.
- Identify the main kitchen variables that affect outcomes: heat, water, time, mixing, and ingredient composition.
- Recognize the major ingredient groups that will recur throughout the course.
- 2
Water, Temperature, and Heat Transfer
- Explain why water is central to most cooking processes.
- Describe the basic ways heat moves through food and cookware.
- Understand how temperature affects cooking speed and texture.
- 3
Salt, Acid, Fat, and Sugar: The Four Everyday Recipe Levers
- Describe the basic functions of salt, acid, fat, and sugar in cooking.
- Connect these ingredients to flavor, texture, and moisture.
- Recognize how small changes in these ingredients can change a recipe.
- 4
Preparing Ingredients: Cutting, Crushing, Dissolving, and Mixing
- Explain how preparation changes cooking speed, flavor release, and texture.
- Understand why surface area matters.
- Describe how dissolving and mixing affect ingredient distribution.
- 5
Proteins Under Heat: Eggs, Meat, Fish, and Dairy
- Define protein denaturation and coagulation in beginner-friendly terms.
- Explain how heat changes the texture of protein-rich foods.
- Recognize common signs of undercooking and overcooking proteins.
- 6
Low-and-Slow Cooking: Collagen, Tenderness, and Moisture
- Explain why some tough cuts improve with long cooking.
- Understand the role of collagen in meat texture.
- Describe the tradeoff between tenderness and moisture.
- 7
Starch and Thickening: Rice, Potatoes, Pasta, and Sauces
- Explain what starch is and how it thickens liquids.
- Describe gelatinization in simple terms.
- Recognize how starch affects texture in grains, potatoes, pasta, and sauces.
- 8
Sugars and Browning: Sweetness, Caramelization, and the Maillard Reaction
- Distinguish between caramelization and the Maillard reaction.
- Explain how sugars contribute to flavor, color, and moisture.
- Recognize the conditions that promote or limit browning.
- 9
Fats, Oils, and Emulsions
- Describe how fats behave differently from water-based ingredients.
- Explain what an emulsion is.
- Understand the role of emulsifiers and mixing in making stable sauces.
- 10
Flour, Gluten, and Dough Formation
- Explain what gluten is in simple terms.
- Describe how water and mixing turn flour into dough.
- Recognize why different levels of mixing give different textures.
- 11
Leavening and Baking: Why Breads and Cakes Rise
- Identify the main sources of gas in baked goods.
- Explain the basic role of yeast and chemical leaveners.
- Describe how structure sets in the oven.
- 12
Acid, Enzymes, and Fresh-Food Changes
- Explain simple ways acids affect color, texture, and flavor.
- Introduce enzymes as natural helpers of change in foods.
- Recognize common examples such as browning fruit and tenderizing marinades.
- 13
Frying, Roasting, and Crisping
- Explain why dry heat creates crisp surfaces and strong browning.
- Describe the role of hot oil in frying.
- Connect moisture loss to crispness.
- 14
When Recipes Go Wrong: Kitchen Chemistry Troubleshooting
- Use basic chemistry ideas to diagnose common cooking failures.
- Match typical problems to likely causes in heat, moisture, mixing, or ingredient balance.
- Apply simple fixes and prevention strategies.
