The heat in dishes containing proteins like meats breaks down the fibers of the meat and makes it tender. It also caramelizes the natural sugars in the meat and develops flavor. In baking breads and cakes, the heat causes the dough to rise and become firm in it's shape but still tender. When cooking vegetables, the heat breaks down the fibers in the vegetables making them tender.
Yes, oil cooks food faster than water because oil has a higher heat capacity and can reach higher temperatures than water. This allows for faster heat transfer and more efficient cooking.
Because the temperatures are high in pressure cooker
It's easier to cook food in the uplands. This is due to the higher altitude allowing for faster cooking time.
Water wont get hotter than boiling otherwise it evaporates. Oil can reach higher temperatures which cooks food faster and makes food crispy, but you can still cook with oil at low temperatures also, like when making pomme fondant.
Increasing external pressure raises the boiling point of water, allowing it to reach higher temperatures without turning into steam. This is the principle behind pressure cookers, where the sealed environment traps steam and increases the pressure, enabling food to cook faster and more thoroughly. As a result, the food can be cooked at temperatures above 100°C (212°F), leading to improved cooking efficiency and flavor.
Preheat your oven before putting the food in it. Be patient and cook at lower temperatures. High heat can dry out the outside of your food long before the inside is cooked to the the desired doneness. Covering the food also helps slow the outside browning if you need to cook it in a hurry and at higher temperatures.
The principle involved in a pressure cooker is that increasing the pressure inside the cooker raises the boiling point of water, allowing food to cook at higher temperatures and reducing cooking time. This results in faster cooking and tenderizing of tough cuts of meat.
It is not true.
The higher pressure raises the boiling point of water.
Food cooks faster in salt water because the salt in the water wraps the food which the chemical reactions from the surface of the food and the salt that contracts and it likes heat the food faster.
Yes, a pressure cooker raises the boiling point of water by increasing the internal pressure. This allows food to cook faster and at higher temperatures, which can help to tenderize tough cuts of meat and reduce cooking times.
Because of its temperature.
