The cooker is now complete! For use just place some blankets and towels inside, and seal a cooking pot in the cooker.

Use[edit | edit source]

The cooker is easy to use. Bring a meal to the proper temperature and leave it there for at least 2 minutes, then seal it in the box. Leave it in the box until cooking is completed. It should be noted that recipes using this method require less spicing and usually 50% more time to cook, so plan accordingly.

Maintenance and tips[edit | edit source]

• Clean your cooker between each use.
• Be sure to wash all blankets and towels used in the cooking process
• Do not leave your cooker in areas where it could get wet.
• Always ensure that your food is fully cooked before consuming
• Experiment with new recipes! Stews and soups work well with this method.
