In the WMF Perfect Plus Pressure Cooker 4.5L, you can quickly and energy-efficiently cook a meal for 7 to 8 people. That's because you can close the lid airtight, so you cook 70% faster than with a standard cooking pot. That's nice, because it saves you both time and energy. Thanks to the special Safe Lock system, cooking is safe. The system locks the lid during use, so that you don't accidentally open it. You can see with the blue pin on the handle if there's still pressure in the pan. You can control the pan via the vegetable or meat program. The meat program cooks with higher pressure than the vegetable program, so that you get a tender result. You can measure liquids directly in the pan, thanks to the volume marking. Note: you need to wash the lid and the handle by hand.
