Roasting coffee beans simply means that you are cooking (griller) them The process lasts about 20 minutes and is done at temperatures ranging between 180 and 250° C Roasting releases the coffee's aroma
a process of converting sulfide minerals to oxides by heating in air at temperatures below their melting points
Cooking in an oven or roasting pan by dry heat without the addition of any substantial liquid This is an effective way to cook meats in a low-fat lifestyle as it draws out fat To exploit this method fully make sure to use a roasting rack or other method to keep the meat out of the fat as it drips from the meat Never eat vegetables cooked with the meat as they absorb the fat Also never cook stuffing or dressing inside poultry as it absorbs the fat and lengthens the cooking time
cooking (meat) by dry heat in an oven (usually with fat added); "the slow roasting took several hours"
Cooking with indirect, dry heat (usually high heat) in an oven, mainly used to cook meat
A process in which a metal ore (such as PbS or ZnS) is transformed into the corresponding oxide (PbO or ZnO) and SO2
Treatment of ore by heat and air, or oxygen enriched air, or other reagent, to eliminate volatile substances and bring about chemical change such as oxidation of sulfides
The treatment of an ore or concentrate with heat and causing partial or full oxidation of the reactive species present in the ore or concentrate Example: Pretreatment of nickel concentrates prior to reverberatory smelting (obsolete), sulphur elimination from zinc concentrates to produce zinc calcine
Cooking larger pieces of relatively tender meat, or whole smaller animals, in dry heat at temperatures from 250-400º In an enclosed pit, the effect is the same as baking in an oven Having less fat interspersed within the muscle, these cuts of meat benefit from roasting, rather than broiling, since the lower temperature, and longer cooking period, allow tougher tissues to become tender Meat may be basted to prevent drying Meat from naturally fed animals may require larding, introduction of fat through the meat with special needles, and barding, covering with layers of fat, to render it tender Meat may also be injected by means of a large syringe, with seasonings, which contain some oil to assist in tenderizing these types of meat This also offers more opportunity for flavoring Time on the grill -- 1-4 hours Time in attendance -- 10-15 minutes
If someone gives you a roasting, they criticize you severely about something in a way that shows that they are very annoyed with you. The team was given a roasting by manager Alex Feguson. give sb/get a roasting if you give someone a roasting, you tell them angrily that you disapprove of their behaviour. In metallurgy, usually the first step in smelting ore to extract metal. The ore is heated in the presence of an abundant flow of air to drive off moisture and, if the metal-bearing mineral is a sulfide, convert it to an oxide. Sulfur fumes from ore roasting have been a major source of environmental pollution in the past
Heating an ore in air, which converts sulfides to oxides Rock: A complex mixture of minerals
