How to use a pressure cooker safely

The right amount of water, low heat once it's under pressure and patience before opening: the golden rules for using a pressure cooker worry-free.

A pressure cooker is safe when it's used the right way. Here are the rules that apply to any model. For the details of yours, the manual in the box always has the final word.

Before it goes on the stove

  • Read the manual. Each model has its own way of closing, locking and releasing steam.
  • Check the valves. They must be clean and clear: they are what release excess pressure.
  • Look at the sealing ring. If it's dry, cracked or loose, replace it before use.

When filling it

  • Never fill it to the brim. Follow the limit shown in the manual. Beans, lentils and grains swell and foam: with them, use even less space.
  • Always have liquid. Steam from the water creates the pressure and cooks the food. Without enough liquid, the pot overheats.

While cooking

  • Once it's under pressure, lower the heat. Low or medium heat keeps the pressure; high heat only wastes gas and overheats the pot.
  • Stay nearby and keep children away from the stove.
  • Use the viewing window. On MTA pressure cookers with a viewing window, you check the cooking and the water level without opening the pot or releasing the pressure.

When opening it

  • Turn it off and wait. Only open it once all the pressure is gone. Never force the lid.
  • Follow the manual to release the steam the right way for your model.

After use

  • Clean the valves and the sealing ring so no food is left to block the steam outlet.
  • Replace worn parts with original parts. Not sure which part fits? Contact MTA customer service.
