The following is a step by step guide to building a retained heat cooker that was designed for the purpose of the Jefferson Community Center workshop 2013

Bill of materials[edit | edit source]

  • 1 Cardboard Produce Box
  • 1 Roll of Aluminum Foil
  • Duct tape
  • Paper (newspaper is preferred)
  • 1 Mylar emergency blanket
  • Scissors

Building Instructions[edit | edit source]

This is an easy process using less than 10 dollars worth of materials

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.
