Finding time in your day for everything you want to do can be a challenge. That's especially true if you try to eat well. Convenience foods can save a lot of preparation time, but they're usually highly-processed and seldom as healthy as homemade meals. For time-stressed cooks, alternatives such as convection ovens and pressure cookers make it possible to prepare traditional meals in less time.
Cooking foods in a conventional oven is relatively inefficient, because air is a poor conductor of heat. That's why water from your tap at 160 to 180 degrees Fahrenheit is painful to the touch, yet you can reach into an 400 F oven without discomfort. Convection ovens increase the air's cooking efficiency by forcing it against the food with a fan. This speeds the transfer of heat from the oven's air to the food, reducing cooking times. The moving air also reduces the effect of hot and cold spots in the oven, and by evaporating moisture from the surfaces of your food convection ovens promote rapid, even browning.
Convection Oven Cooking
If you're using a convection oven to prepare meals, you can shorten your baking or roasting time by roughly 25 percent. That's a significant convenience, especially during the heat of summer when you want to minimize your oven's use. Roasts or turkeys quickly develop a rich, brown color and deep flavors, and casseroles rapidly reach a food safe temperature of 165 F. Small entrees such as pork chops, fish fillets or breaded chicken cook quickly, becoming golden on the outside, while remaining tender and juicy on the inside.
The cooking time of boiled, steamed or stewed meals is determined by the boiling point of water. Water conducts heat more efficiently than air, but at sea level it's limited to a maximum temperature of 212 F, and at higher altitudes it's even lower. Pressure cookers address this by trapping steam from the boiling water inside a tight lid. As the steam continues to expand it increases the atmospheric pressure on the water, simulating the effect of being below sea level. This can increase the boiling point of water inside the pot to as high as 250 F, greatly shortening cooking times.
Pressure cooking works in several stages and requires a bit of attention, but it's very fast. Most meals take 15 minutes or less, once the pot comes up to pressure. Fill your pressure cooker with the recipe's ingredients, check the lid to ensure the valves operate freely and the gasket is undamaged, and lock the lid into place with the valve open. Heat the pot until steam escapes freely, then close the valve and bring the pot to its high or low setting. At that point, start timing your recipe. When it's done, either let the cooker cool or use the quick-release option, as directed in your recipe.
