This very simple, but very innovative cooking bag should replace your slow cooker. You just have to boil your food for only 5 minutes and put your hot pot in the wonderbag. The bag has an insulated design and therefore keeps your food safely cooking up to 12 hours, without additional energy. Therefore it helps reducing carbon emissions and it saves water, because less evaporation occurs. On top of that, less food will be wasted from burnt pots, because of the bags insulation. Because it was originally developed to conserve cooking energy in developing nations, for every purchased wonderbag, a wonderbag is also sent to a family in Africa.
