The HotBag Project promotes cooking with retained heat, with particular relevance to all food cooked with water (rice, porridge, potatoes, vegetables, soups, stews, dried beans, and even a whole chicken). The HotBag is a companion to any and every stove, at home or away. Once food is heated to boiling point on a stove, cooking can continue in a HotBag.

The lightweight, non-bulky insulation includes a heat-reflective foil which also acts as a steam barrier. Using a HotBag does not lengthen normal cooking time, while it reduces stove time by two thirds. Food remains hot for 3 to 5 hours and longer. Being portable, the HotBag enables hot dishes to be transported in a vehicle while cooking, and it is also useful as a cooler bag for grocery shopping.

The project aims to achieve recognition of the benefits of the HotBag as an essential cooking item in every household:

  • Environmental benefits through 50% less stove usage in normal cooking procedures
  • Enhanced safety and convenience around cooking
  • Makes meals more delicious and more nutritious
  • Also useful as a coolerbag

HotBag cooking does not mean a longer cooking time: it means less stove usage. Here is an example:

    5 min. is all that is needed to simmer white rice on the stove (10 min. for brown rice)
 + 20 min. additional cooking time in a HotBag
 = perfectly cooked rice in normal time (and no danger of burned pots)

The HotBag Project is a South African initiative, and the HotBag is a registered design.
