Wonderbag? Wondertea!

So like I said the other day, at the Caravan and Camping (or whatever it was called) show, we bought a Wonderbag.
The woman we got it from was very chatty, very helpful, and very clear about how good these are. They are made of material and some are filled with polystyrene, and some aren't. Ours isn't. It's full of foam chips, which are recycled.  There's more technical details on their website, here.












So first I had to find a suitable sized pot.
Then I made casserole the way I usually would.



It needs to be made in a pot with a tight fitting lid.
Then it goes into the Wonderbag.  I put mine in on a teatowel.  I'm very good at spilling things sometimes, and I do not want to mark this!






The 'lid' goes on top of the pot, and then the drawstring is drawn up tight.
Then it's just left on the kitchen side.  For real.  Just left.  This is the slightly difficult bit for me, because I want to poke what I'm cooking.  If I was to open the bag, then it wouldn't work, because the whole point is that it is a massive insulating bag.
This isn't a new idea - hayboxes and the like have been made for centuries, but this is great.  Not only does it match the colour of the glorious Brian, (although it is reversible, should we every get a grey camper....)
Obviously the big question is "Does it work?"  Well, I'll let you know in about 4 hours.....


update!

It was six o'clock in the end before we got around to eating tea. It had been in the Wonderbag for just under 5 hours. It was gorgeous! It was fairly hot, everything was cooked through nicely (although the carrots could have done with a bit longer according to the man) and even the meat was tender and juicy.

Now, the man tells me that this is Not a cooking blog, and so I'm Not to talk lots about cooking. So I won't. Probably.

Anyway, the upshot of the wonderbag is that it was great! Loved it! (An Wonderbag don't know I'm writing about them, so I don't have to say that!)

Now to stick cartoon pieces on the fridge!
