Y1.5.3 Cooking Methods
Objectives • Describe dry heat cooking methods and list the foods to which they are suited • Describe moist heat cooking methods and list the foods to which they are suited • Describe combination cooking methods and list the foods to which they are suited
Intro • Beyond the hundreds of recipes, there are variety of cooking methods, each producing a different result • Using the appropriate cooking techniques (methods) will produce the desired results
Heat Transfer • Heat is a type of energy • Absorbed energy, vibration, expansion, collision, transfer of energy • Heat energy is transferred to foods via conduction, convection or radiation • Heat then travels through food by conduction
Heat Transfer • Conduction: movement of heat from one item to another through direct contact • Some materials conduct better than others
Heat Transfer • Convection: transfer of heat through a fluid which may be liquid or gas • Natural or mechanical
Heat Transfer • Radiation: energy is transferred by waves of heat or light striking the food • Infrared, electric or ceramic element, coals • Microwave, radiation exciting water molecules
Effects of Heat Proteins Coagulate • Proteins are long, coiled chains of molecules held together by bonds. Light can pass through, raw egg whites are clear, raw meat translucent • Exposed to heat (air or acid) the bonds break, and the coils unwind (denatured)
Effects of Heat-Proteins Coagulate • The denatured proteins become caught up on their bonds and form a coagulated 3-dimensional mesh. Light is reflected, product is opaque • The longer the heat, the higher the temperature, the tighter the coagulated mesh becomes, squeezing out the water. • The key to moist proteins is gentle heating
Effects of Heat • Starches Gelatinize • When starch granules reach a temperature of approximately 140°F. they absorb additional moisture- up to 10 times their own weight- and expand.
Effects of Heat • Sugars Caramelize • As sugars are heated above 320°F. they caramelize, adding flavor and causing the product to darken.
Effects of Heat • Water Evaporates • Pâte à choux, puff pastry, crust, reduction.
Effects of Heat • Fats Melt • As fats melt, steam is released, and fat droplets are dispersed throughout the product • Tenderizes and shortens gluten strands • Different fats melt at different temperatures
Three General Types of Cooking Methods • Dry heat cooking • Moist heat cooking • Combination cooking
Dry Heat Cooking • Food prepared using dry heat must be naturally tender or prepared by adding moisture • Barding: wrapping with strips of fat before cooking so it bastes while cooking. • Larding: inserting long thin strips of fat with a larding needle to baste from the inside. • Marinating: Soaking in a combination of wet and dry ingredients to provide flavor and moisture.
Dry Heat Cooking Without Fat With Fat Sautéing Pan-frying Stir-frying Deep-frying • Grilling • Broiling • Roasting • Baking
Dry Heat Cooking Dry Heat Cooking without Fat • Grilling: cooked on a grill rack above the heat source • Highly flavored outside, moist inside • Smokey, slightly charred flavor as the fats melt and drip on the heat source
Dry Heat Cooking Without Fat • Barbecuing: another form of grilling • basted repeatedly with a sauce, pan drippings, or other liquid, keeping food moist
Dry Heat Cooking Without fat • Broiling: rapid cooking method that uses high heat from a source located above the food • Quick, high heat methods require tender cuts of meat, poultry, fish and some fruits and vegetables
Dry Heat Cooking Without fat • Roasting: cooks food by surrounding the items with hot, dry air in the oven • Most often used with large cuts of meat, whole birds, or fish
Dry Heat Cooking Without fat • Baking: cooking food in an oven without liquid • While roasting generally refers to meats and baking generally refers to breads and pastries, the terms are fairly interchangeable
Dry Heat Cooking With fat • Sauté: food cooks rapidly in a small amount of fat over relatively high heat • Stir-fry:food cooks rapidly in a small amount of fat over relatively high heat, while being constantly stirred • Bite-size pieces of food
Dry Heat Cooking With fat • Sauté • Small amount of fat over relatively high heat • To jump • 212-420 degrees, requires judgment • Start with dry pan, add oil • Too little oil, too cool, too little time: stick
Dry Heat Cooking With fat • Griddling • Cooked on a hot, flat surface (or cast iron pan) • Less fat than sauté
Dry Heat Cooking With fat • Pan-fried: foods are often coated with batter or breading, and then cooked in oil over less intense heat • uses more oil than sauté, about half way up the food being cooked • Hold only a short while
Dry Heat Cooking With fat • Deep-fried: also called French fried, breaded or batter-coated food is immersed in hot fat • Swimming method: gently dropped • Basket method: placed in basket, lowered • Double basket method: hold food in place • Keep food dry
Deep-fry, cont. • Outside is fried, inside is steamed • Blanch fry 275°F. 10 min., cool/freeze then 350. • Hold 250°F. oven. • Large pot ⅓ full.
Dry Heat Cooking Deep-fry, cont. • Recovery time: time it takes oil to reheat to the correct cooking temperature once food is added • Smoking: temperature at which fats and oils begin to smoke, which means that the fat has begun to break down (425°F.) • Oil temperature for deep fry is usually 325°F to 375°F
Dry Heat Cooking Deep-fry, cont. • Batter: combines wet and dry ingredients (primary dry, liquid, binder) • Breading: same components as batter, but not blended together. (Dredge in flour, then egg, then crunchy ingredient) • As much as 35% of the flavor of a deep-fried food comes from the oil in which it’s cooked
Moist Heat Cooking • Moist heat cooking techniques produce foods that are delicately flavored and moist with a rich broth, which can be used as a base for a sauce • E.g.. One pot New England boiled dinner
Moist Heat Cooking • Boil • Simmer • Poach, shallow poach • Blanch • Steam
Moist Heat Cooking • Boil: to cook food in a liquid that has reached the boiling point (212°F) • Action of bubbles prevents use of delicate foods • High temperature could toughen the protein of meat, fish, and eggs
Moist Heat Cooking • Simmer: (185°F to 200°F) • Bubbles in the liquid rise gently and just beginning to break the surface
Moist Heat Cooking • Blanch: placed in boiling water for a short time • Usually shocked: plunged into ice water to stop cooking • par-cooking • Tomatoes to peel • Green beans finished with sauté • Larger pieces
Moist Heat Cooking • Poaching: food is completely submerged in liquid that is kept at a constant, moderate temperature (160°F to 180°F) • Water shows some motion, no bubbles • Fish, seafood, delicate sausage, mousselines, root vegetables, legumes, eggs • Fat: confit
Moist Heat Cooking • Shallow poaching: cooked in a liquid bath and steam • Best suited for portion size pieces cooked at last-minute • Partially covered by a liquid containing an acid and herbs or spices in a covered pan • Liquid, cuisson used as sauce base
Moist Heat Cooking • Steaming: cooks food over, not in, boiling water • Tender cuts, small pieces • No carmalization • Retains color, shape, flavor, nutrients • Keep covered
Combination Cooking • Uses both dry heat and moist heat methods • Good for less tender cuts • Allows for caramelization and longer cooking time • Braising • Stewing
Combination Cooking • Braising: Seared in hot oil, add liquid, finish in oven or Dutch oven • Longer cooking time tenderizes connective tissues of tough cuts • Vegetables can be added • Released liquid used for sauce
Combination Cooking • Types of braising • Daube: (DAWB) often beef, red wine, marinated • Estouffade: (ess-too-FAHD) French term refers to both braising method and the dish itself (a beef stew made with red wine) • Pot roasting: American term for braising
Combination Cooking • Stewing: similar to braising, bite sized pieces that are blanched or seared • Requires more liquid
