Amazon.com's online shoppers in the US are giving rave reviews to the Wonderbag, a traditional slow cooking system updated by South African social entrepreneur Sarah Collins who is now marketing it globally in collaboration with Unilever (and its Knorr brand). Forbes tells the story here.
The genius behind Sarah’s simple but profound invention is that the Wonderbag is a non-electric, heat-retention cooker that allows food that has been brought to a boil, to continue cooking after it has been removed from the fuel source. Today, due to Sarah’s passion, energy, and perseverance, 750,000 bags have been distributed, first round of carbon credits registered and issued, production capabilities in Rwanda, Mexico and Turkey with launches in Kenya, Nigeria and Somaliland. 14,000 bags have been sold in the UK, Europe and USA, with a buy-one-give-one model to support getting Wonderbags into humanitarian relief.
