    Study Notes

    Basic Principles of Cooking

    • A written recipe cannot be 100% correct.
    • A cook's judgment is based on experience and understanding of raw materials, basic cooking principles, and food science.
    • Ever since Carême, professional cooking has been based on procedures and methods, not just recipes.
    • Chefs have improved their knowledge and skills by understanding the science behind cooking.

    Heat and Food

    • Heat is a form of energy associated with the motion of atoms or molecules.
    • When a substance absorbs heat, its molecules move faster, resulting in a higher temperature.
    • Temperature is the measurement of molecular activity.
    • Fast-moving molecules in hot substances come into contact with slower molecules in cold substances, transferring energy, causing heating.
    • Food is composed of proteins, fats, carbohydrates, water, and smaller components such as minerals, vitamins, pigments, and flavor elements.

    Carbohydrates

    • Starches and sugars are carbohydrates and are present in fruits, vegetables, grains, beans, and nuts, meats, and fish.
    • Caramelization and gelatinization are two most important changes in carbohydrates caused by heat.
    • Caramelization is the browning of sugar.
    • Gelatinization occurs when starches absorb water and swell.

    Fruit and Vegetable Fibers

    • Fruit and vegetable fibers are complex substances that give plants structure and firmness.
    • Fiber cannot be digested.
    • Cooking softens fruits and vegetables as fibers break down.
    • Acids and sugar can make fibers firmer, while baking soda can make them softer.

    Proteins

    • Proteins are long chains of amino acids.
    • These chains normally form tight coils but will gradually unwind during heating.
    • At this point, the protein is denatured.
    • Further heating leads to coagulation, causing the protein coils to unwind and further toughen the protein.
    • Most proteins coagulate between 71° and 85° Celsius.
    • Meat and fish, cheese, eggs, beans, bread, hummus, nuts, and seeds are sources of protein.

    The Maillard Reaction

    • The Maillard reaction occurs when proteins are heated to 154° Celsius.
    • Amino acids in the protein react with carbohydrate molecules, triggering a complex chemical reaction.
    • This reaction results in a brown color and richer flavor.
    • This reaction only takes place on the dry surface of the food.
    • Special proteins in meats, known as connective tissues, can be dissolved by slow cooking, aided by acids like lemon or vinegar.

    Fats

    • Fats can be solid or liquid at room temperature.
    • Liquid fats are called oils.
    • When solid fats are heated, they dissolve, with melting points varying.
    • Continued heating causes fats to rapidly deteriorate and begin to smoke, with different smoking points for various fats.
    • Fat sources include meats, poultry, fish, eggs, milk and milk products, nuts and grains, and fruits and vegetables. Fats are also important cooking mediums, such as frying.

    Cooking Methods

    • Moist heat methods use water or water-based liquids to transfer heat.
    • Methods include boiling, simmering, poaching, blanching, steaming, braising, and stewing.
    • Dry heat methods use hot air, hot metal, or hot fat for heat transfer.
    • Methods include baking/roasting, barbecuing, pan smoking, grilling, griddling, pan-broiling, sautéing, pan-frying, and deep-frying.
    • Sous-vide, a French term meaning "under vacuum," involves vacuum-sealing food in plastic bags before cooking them at a precise temperature.
    • Molecular gastronomy manipulates food ingredients in new and innovative ways using technology.

    Building Flavors

    • Flavor profiles are the harmony of tastes and aromas created by combining ingredients.
    • Primary flavors come from the main ingredient.
    • Supporting flavors enhance the main ingredient, with each ingredient having a purpose.
    • Ingredients can work together by harmonizing or contrasting.
    • Simpler flavor combinations are usually better than complex ones.
    • Classic flavor recipes are the best way to study traditional cuisines around the world.
    • Seasoning enhances the natural flavor of the main ingredient.
    • Flavoring adds a new flavor to food.
    • Most flavorings need heat to release their flavors.
    • Too much cooking can result in a loss of flavor.

    Herbs and Spices

    • Herbs and spices are flavorings, with herbs often from temperate climates and spices from tropical climates.
    • A list of common herbs and spices includes Allspice, Basil, Cilantro, Chili powder, Chipotle, Cinnamon, Cumin, Garlic, Marjoram, Onion, Oregano, Paprika, Parsley, Rosemary, Salt, Thyme, and Black Pepper.
