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.
