1 temper
1. To slowly bring up the temperature of a colder ingredient by adding small amounts of a hot or boiling liquid, or even applying heat carefully Adding the heat or hot liquid gradually prevents the cool ingredient, such as eggs, from cooking or setting. The tempered mixture can then be added back to a hotter liquid for further continued cooking. This process is used most in making pastry cream and the like.2. To bring chocolate to a state in which it has snap, shine and no streaks ( feathers). Commercially available chocolate is already tempered but this condition changes when it is melted. Tempering is often done when the chocolate will be used for candy making or decorations. Chocolate must be tempered because it contains cocoa butter, a saturated fat which has the ability to form crystals, chocolate is melted and cooled. Dull grey streaks form and are called bloom or feathers. The classic tempering method is to melt chocolate until it is totally without lumps (semisweet chocolate melts at a temperature of 104 degrees F.) One third of the chocolate is then poured onto a marble slab then spread and worked back and forth with a metal spatula until it becomes thick and reaches a temperature of about 80°F. The thickened chocolate is then added back to the remaining 2/3 melted chocolate and stirred. The process is repeated until the entire mixture reaches 88-92 degrees for semisweet chocolate, 84-87 degrees for milk or white chocolate. -
2 deglaze
To remove browned bits of food from the bottom of a pan after sauteing, usually meat. After the food and excess fat have been removed from the pan, a small amount of liquid is heated with the cooking juices in the pan and stirred to remove browned bits of food from the bottom. The resulting mixture often becomes the base for a sauce.♦ A process of adding liquid to a hot pan in order to collect the bits of food which stick to the pan during cooking. This is most common with sautéed and roasted foods. Wine, stock, and vinegar are common deglazing liquids.♦ To dissolve the thin glaze of juices and brown bits on the surface of a pan in which food has been fried, sauteed or roasted. To do this, add liquid and stir and scrape over high heat, thereby adding flavor to the liquid for use as a sauce. -
3 liaison
The process of thickening a sauce, soup, or stew. This includes all roux's, starch and water mixtures slurries), beurre maniere‚ Panada, and egg yolks with or without cream. Egg yolks must be tempered with hot liquid before adding to the liquid in order to prevent curdling.A thicking or binding agent, commonly egg yolk or heavy cream to ticken soups & sauces -
4 margarine
A solid fat invented in 1869 by the French chemist Henri Mege- Mouries. Margarine was first invented to replace butter in cooking and baking. It was then made solely of beef fat. Margarine is now made with a variety of fats, alone or with others, along with the addition of water, whey, yellow coloring, and vitamins. Beef fat is still used today, but with a higher consciousness towards a healthier diet, it is used sparingly by many -- Margarine can pose a trans fatty acid problem within digest as well. The Color of margarine is derived mainly from Achoite Marinate -( From the Latin - Marine to submerge -- To soak food in a seasoned liquid mixture for a certain length of time. The purpose of marinating is to add flavor and/or tenderize the food. Due to the acidic ingredients in many marinades, foods should be marinated in glass, ceramic or stainless steel containers. Foods should also be covered and refrigerated while they are marinating. When fruits are soaked in this same manner, the process is called macerating. -
5 steam
To cook food on a rack or in steamer basket over a boiling liquid in a covered pan. Steaming retains flavor, shape, texture, and nutrients better than boiling or poaching.To cook in steam in a pressure cooker, deep well cooker, double boiler, or a steamer made by fitting a rack in a kettle with a tight cover. A small amount of boiling water is used, more water being added during steaming process, if necessary. -
