About Wonderbag

Founded by Sarah Collins in 2008, the Wonderbag was developed as a solution to the South African energy shortage forcing blackouts across the country. The aim was to help families to continue cooking daily meals even with the absence of power. Time spent collecting firewood and tending a fire can now be spent in education or employment.

When you purchase a Wonderbag, you’re investing in the environment and supporting the manufacturing community in South Africa.

Which pot do I use?

Use a pot or pan with short handles and a tight fitting lid. Long pan handles will stick out of the bag. For best results, choose a pot that will be almost full with your recipe. This will help maintain the ideal cooking temperature.
Some pots that are suitable for the Wonderbag are: De Buyer Affinity Stainless Steel Casserole Pan with Lid and De Buyer Inocuivre Copper Stockpot 24cm.


The fabric of the bag in polyester cotton. The insulation material is repurposed foam chips. These would normally go to landfill, but Wonderbag buys them as large chunks, and cut them up to smaller pieces to be better suited as filling.
