Steam cooking vs. pressure cooking

While pressure cooking and steam cooking both utilize steam, there are some differences between the two methods. Steam cooking typically involves using a dedicated steamer or steaming basket, where the food is placed above boiling water and cooked by the hot steam. Pressure cooking, on the other hand, involves cooking food under high-pressure steam generated inside a sealed pot. Pressure cooking offers faster cooking times and more intense flavors due to the high-pressure environment.

Recommended cooking times for different foods

The cooking times for various foods in a pressure cooker can vary. Some general guidelines include cooking meats like chicken or beef for around 20-30 minutes per pound, depending on the desired tenderness. Vegetables usually require shorter cooking times, typically around 2-5 minutes, to retain their texture and color. Grains like rice or quinoa can be cooked in just a few minutes, while beans and legumes may require longer cooking times to soften. It is always advisable to consult specific pressure cooker recipes or cooking charts for accurate cooking times.
