Grilling is a form of cooking that involves dry heat applied to the surface of food, commonly from above or below.Grilling usually involves a significant amount of direct, radiant heat, and tends to be used for cooking meat quickly and meat that has already been cut into slices...

Baking
Baking is the technique of prolonged cooking of food by dry heat acting by convection, and not by radiation, normally in an oven, but also in hot ashes, or on hot stones. It is primarily used for the preparation of bread, cakes, pastries and pies, tarts, quiches, cookies and crackers. Such items...

Roasting
Roasting is a cooking method that uses dry heat, whether an open flame, oven, or other heat source. Roasting usually causes caramelization or Maillard browning of the surface of the food, which is considered by some as a flavor enhancement. Roasting uses more indirect, diffused heat , and is...

Sautéing
Sautéing is a method of cooking food, that uses a small amount of fat in a shallow pan over relatively high heat. Ingredients are usually cut into pieces or thinly sliced to facilitate fast cooking. The primary mode of heat transfer during sautéing is conduction between the pan and the food being...

Browning is the process of partially cooking the surface of meat to help remove excessive fat and to give the meat a brown color crust and flavor through various browning reactions. Ground meat will frequently be browned prior to adding other ingredients and completing the cooking process...
and blackening, are typically used to sear all sides of a particular piece of meat, fish, poultry, etc. before finishing it in the oven. To obtain the desired brown or black crust, the meat surface must exceed 150 °C (300 °F), so searing requires the meat surface be free of water, which boils at around 100 °C (212 °F).
Although often said to "lock in the moisture" or "seal in the juices", searing has been demonstrated to result in a greater net loss of moisture versus cooking to the same internal temperature without first searing. Nonetheless, it remains an essential technique in cooking meat for several reasons:

. - The appearance of the food is usually improved with a well-browned crust.
- The contrast in taste and texture between the crust and the interior makes the food more interesting to the palatePalateThe palate is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but, in most other tetrapods, the oral and nasal cavities are not truly separate. The palate is divided into two parts, the anterior...

carried out such a test in episode EA1H22, Myth Smashers.) As early as the 1930s, such experiments were carried out; the seared roasts lost the same amount of moisture or more. (Generally more, since searing exposes the meat to higher temperatures.)
Moisture in liquid and vapor form continues to escape from a seared piece of meat. For this reason, searing is sometimes done at the end of the cooking process to gain the flavor benefits of the caramelization, as well as the benefits of cooking for a greater duration with more wetness.
