Pressure cooking is a method of cooking food quickly by using steam and high pressure. A pressure cooker traps steam inside, which raises the temperature above the normal boiling point of water. This allows food to cook faster while retaining moisture and flavor, making it a popular choice for busy cooks. Using a pressure cooker can save time and energy, as meals that typically take hours can be ready in just minutes. It's great for preparing tough cuts of meat, grains, and even soups. Plus, many modern pressure cookers come with safety features, making them easy and safe to use.
