Wonderbag - Saving the planet... one delicious meal at a time

Wonderbag is an electricity-free heat retention cooker in which you can cook anything from stews and curries to a golden syrup sponge pudding. Simply heat up your pot of food on the stove, kick-starting the cooking process, and then place it in the Wonderbag.

Unlike conventional slow cookers which are often left plugged in for anything up to 8 hours, when using a Wonderbag you simply bring the food to the boil on the hob and then place the pot directly into the Wonderbag and leave to cook.

Wonderbag's clever insulating design allows food that has been brought to the boil to finish cooking without using any additional energy. As well as significantly reducing C02 emissions, replacing your traditional slow cooker with a Wonderbag will ultimately help you to leave home without keeping the electricity on.
