Cloth Cooker

This insulated bag is actually a portable slow cooker. It uses heat retention and a fraction of the energy to cook your food while camping, at picnics, or even just a dinner party. Start the cooking process like you usually would, by bringing your soup, stew, or other meal to a boil. Then remove the pot from the heat and place it inside the wonderbag. The insulation will let it keep cooking without any additional electricity or fuel. Maker Sarah Collins is based in South Africa, where some people—particularly women and children—spend a huge amount of time gathering wood for cooking and heat. The effort it takes keeps them out of school and work, and the fire has various health hazards for the people cooking. Sarah created wonderbag as more than just a cooking accessory, it’s “a catalyst out of poverty.” When you buy a wonderbag, you’re also helping fund the wonderbag Foundation, which is committed to giving more families in need access to an easier, safer, more environmentally friendly way to cook.

Quick Questions

How is the wonderbag different from other slow cookers?

Powerless is powerful when it comes to the wonderbag. Where most conventional slow cookers utilize power to keep your food cooking, the revolutionary insulated technology keeps your food cooking for up to 12 hours after it is brought to a boil by simply retaining heat. And because it is not on direct heat, the food will never overcook or burn.

Can this be used for anything other than slow cooked recipes?

From meaty stews and vegetable curries, to simple rice, beans, pasta, and soups, the wonderbag cooks food beautifully and thoroughly. Meat is perfectly tender and vegetables retain their flavor and texture. It can also keep food and drinks cold, too!

How do I know how long to cook foods?

The recommended time for grains is 1 hour; chicken is 3 hours; dried beans 3-4 hours; and red meat 4 hours or more. While the length of time that you cook depends upon the recipe, we recommend boiling until all ingredients are heated through before placing your pot in the wonderbag. The longer you leave your food to cook, the tenderer it will be. The wonderbag comes with a recipe booklet to provide ideas and guidance; after a few times using it, you will get the hang of it! Also, see our cooking times chart for more information.

How long does food in the wonderbag stay cooking and hot?

This depends on a number of factors: the amount of food (the fuller the pot, the better), how dense the dish is (the denser, the longer it stays hot), even the weather outside (the hotter the weather, the longer the dish stays hot!). However, on average, dishes will stay hot (over 185ºF/85 ºC) for approximately four hours and 150ºF/65ºC for a further four hours.

    @Caroline Great question! You can use a sponge to clean the wonderbag or place it in a gentle machine wash, separately. The insulation is made from recyclable foam chips that have been diced up into discs with a machine in our South African factory. The foam chips are then inserted into the bag according to its weight and size. Once the bag is pulled tightly, it traps the heat achieved on the stove or in the oven and will continue the cooking process for you. Thank you, Caroline.

    @Eldon Thank you for your terrific question. Depending on the dish you are cooking, most recipes stay well above 135° F for at least 4 or 5 hours, some up to 8 hours and 12 hours. Once you start using the wonderbag, you will quickly get a feel for it. The bag comes with a recipe book and will help you understand cooking times for different dishes, meats, rice etc.

    Wanting to buy for Gifts but I am not sure what size "cookware" my friends have... will a large Wonderbag work with a smaller "pot"... will it adjust small enough to work properly?

  • Chantelle

    11/17/2017 11:35 AM

    @Joan Great question! Our large wonderbag will fit a short handled pot sized between 2-12 quart, and yes, if you were using a smaller pot, it will work just as well. Always use the right size pot for the amount of food you wish to cook and use a pot with short handles.

    We recommend using copper, steel, aluminum, enameled cast iron, cast iron and glassware pots. If you use cast iron, clay or ceramic, you must put a trivet under the pot (inside the bag) to avoid damaging the fabric from the heat of the bag.

    Some wonderbag users like to put a tea towel under the pot in their wonderbag to protect it from any spills.

    @Ramona This is an excellent question! Cooking meats, poultry or mutton is one of my favorite things to do with the wonderbag. I spend about 10-15mins prepping the meat, and the wonderbag does the rest and cooks it better than I ever could on the stove or oven. So with meats, the wonderbag works really well, here’s what you do:

    Brown the meat off in the pot (beef, lamb, pork, turkey etc), set the meat aside. Then you would add ingredients for the meat to cook in (onions, garlic, broth), place the meat back in the pot, bring the dish to the boil, then place into the wonderbag. The wonderbag will cook the meat for the specified time. You would then finish the meat off under the broiler/grill or on the BBQ/grill. So the finished dish is slow cooked on the inside and crispy on the outside. There’s no carving to be done because the meat will be so tender, it will fall off the bone. That’s how you roast meat with a wonderbag.

    OR

    Slow cook the meat for pulled pork or chicken to add to pasta, salads, tacos and other dishes you love.

    wonderbagworld.com has a recipe section where you can look up lamb or other meat dishes if you wanted to take a look. It will give you a great idea of how you would cook the meal you have in mind. Each wonderbag also comes with a cookbook and helpful information for learning how to use your wonderbag correctly.

    @D Thank you, D! The bags are constructed in South Africa but the foam comes from many parts of the world. We take foam from the car industry and the furniture industry, foam that would have otherwise ended up in landfill, and we recycle this foam, and dice it up with our machine in our factory.
