Review: Used to LOVE this bag, time for a new experiment years later - When I purchased this, it was $50. That was in 2014. I love, love, LOVE this bag!! I've used it consistently, cooking crock pot meals and bone broth. I don't know if the quality has changed with the newer bags over the years; it's a shame if it has because this bag is truly a beast. I start my food in a crock pot, put a towel in the bottom of the bag, then turn off the crock pot when I'm ready to leave the house, unplug and put the entire crock pot in the bag, place the 'hat' atop the slow cooker's lid, tighten the drawstrings and think no more about it. I don't like anything 'on' when I'm not home, so I appreciated the fact, that my food could keep cooking when I'm not home, safely. I pulled it out today, after a few years of inactivity. Due to surprisingly negative reviews, I'm going to make something in a small cast iron dutch oven this week (holds 3 or 3 1/2 qt of food). I'm going to see what happens when I use this in the bag as opposed to the slow cooker, just to see what's what. My plan is to prepare the meal at night and see what happens by morning. I'll report back when I do, hopefully with the same great results I'm used to seeing. Before, I used to use the bag mostly for making bone broth since that had to cook for 2 days or so. I'd start the slow cooker, let it cook all night, put the whole crock pot in the Wonderbag in the morning when it was time to go to work, then put it back on slow cook in the evening. Everything stayed burning hot and kept cooking. I'm going to enjoy this little experiment. I won't be making bone broth, maybe beans or chili to start.
Review: Works as expected -- versatile, efficient, and inspiring! - Update: Since the initial purchase we have used the Wonderbag repeatedly to make yogurt and to make things I used to cook in an electric slow cooker. My sweetie has declared, "you bought a cool thing!" Most recently I put a whole chicken in the pot, brought it to a boil with plenty of water, and snuggled it into the WB to cook while I was off running errands. I pulled it out several hours later and deboned the tender cooked chicken to make soup. I love this thing. Storing it is no problem for me because it looks fine on my couch when not in use--like a big round pillow. After the initial heating there's no consumption of fuel no lit burner to worry about, no danger of overheating or cooking dry. This is a convenient device for modern cooks that utilizes resources wisely and reduces wasteful over-consumption of resources. Every home should have one. Original Review: I was curious enough about the Wonderbag to give it a try and confident enough to make moose stew the first experiment. Per instructions I used a short handled heavy pot. After browning the meat and aromatics on the stove I added some flour for thickening and my chopped raw veggies. I made sure there was enough liquid to cover everything and that the pot was pretty full. After bringing it to a boil I put the lid on and let it simmer for about 20 minutes so everything had a chance to heat through. Then I popped the whole shebang in the dishtowel-lined Wonderbag, pulled the drawstring tight, and left it on the counter for 8 hours. It was plenty hot still (140 degrees) when I opened it up and everything was cooked but not mushy. The stew needs a little more thickening since there's no evaporation inside the bag, but not bad for the first try. I did this as an overnight experiment so I wouldn't be tempted to open it early and let the heat escape, so I will be refrigerating the stew and re-heating it on the stove for tonight's dinner and will thicken it a little more at that time. I am looking forward to trying this for rice, beans, posole, etc. I've used traditional slow cookers for years but in addition to the environmental benefits of the Wonderbag, I think the gentleness of the retained heat cooking method will be advantageous. An electric slow cooker is a great convenience but does have a tendency to turn everything into a chunky, colorless mush if left for too long. If you've used one you know what I mean! Yes, the Wonderbag is bulky. Since it retains heat through insulation, I expected this to be the case. I store other bulky things like a pressure cooker so the dimensions don't worry me overmuch. Yes, it comes vacuum-sealed into a much smaller package and must be "fluffed" prior to the first use. This wasn't terribly onerous. My only concern was that my cat would find it and take a nap in there. The instructions packed with the Wonderbag are pretty clear. However, people are people and not everyone reads and follows instructions. I can see the potential for very poor results, including food-borne illness, if users are careless or lack a good heavy pot with a tight lid. If you open it up midway through to peek, you are going to lose the heat. If you leave it sitting around for 18 hours, it's going to cool off and allow bacterial growth. Any food preparation method has drawbacks and this is no exception. It's an insulated bag, not a magic spell. Don't be surprised that the result is not "the same" as a an electric slow cooker. You can't have it be "the same" and "different" simultaneously.

## Questions & Answers

**Q: I don't think I'd use this, but I'd like to donate a couple.  How would I do that?**
A: Hi, you can make a donation at www.wonderbag.org. 100% of your donation will go toward distributing Wonderbags to people who need them. thank you!

**Q: I'm wondering about using this for a hiking/camping situation to conserve scarce fuel.  Can anyone tell me how much it weighs?  I need to know the actual weight to determine if it is reasonable to carry in a backpack. thanks.**
A: The mini size ones are 2 quart pot size, $35. Wonder if it is any better than a 64 oz/2 qt wide mouth vacuum thermos. Or using a 1.5 liter pressure cooker to conserve fuel.

**Q: How can I donate to this cause without buying one for myself?**
A: Buy one for a friend or donate one to a charity?

**Q: Anyone use this to make yogurt?**
A: I didn't get good results. The problem is, you can't bring yogurt to a boil, which Wonderbag requires. You need yogurt to incubate for 6-10 hours at around 110 degrees F. If it cools too much, the good bacteria produce slime, so you get ropey yogurt, like I got from the Wonderbag.

### ⭐⭐⭐⭐ Also makes a dandy cat bed
*by K***N on October 3, 2014*

I bought this product last winter and have used it a number of times; it is not perfect, but I am learning how to make good use of it in my kitchen. With electricity rates expected to go up by 37% this winter, I expect to use it regularly. As the instructions state, food has to be brought to a boil and cooked for a period of time before you put it in the bag. It's been great for dried beans, sturdy whole grains (rice, not so much) and dense root vegetables (carrots, potatoes, etc). It seems to work best with full pots rather than half-empty ones. I don't eat meat, so I can't address that issue. It is important to note that you don't have to cook a dish entirely in the wonderbag--if you're cooking something that takes a long time at a low temperature, like beans, you can pop it in the wonderbag for a few hours, then put it back on the stove for a short final cooking. I often put my beans in the bag for few hours, then put them back on the stove for a few minutes to add other ingredients that don't need to cook as long, then return the pot to the wonderbag for further cooking. A large pot of beans might spend a half hour total on the stove, as opposed to 3 hours or more. I like it better than a crock pot because I have never had one that had good temperature control--and it uses a lot less energy. It may not suit people who want to walk away from the food for twelve hours and come home to a meal that's completely ready to eat. But you don't have to worry about the house burning down in your absence. I like that it is made from recycled foam and I was also happy to pay extra to provide one to a family in Africa. We are fortunate in this country that we don't have to worry about having enough fuel to cook our food. I wish that it was more moisture and stain-resistant--I haven't tried to wash it, and hope I won't have to. Lastly, cat owners should be aware that a still-warm Wonderbag is irresistible to cats! If you leave it out, don't be surprised to find a very happy cat occupying it.
