I can't for the life of me remember the name of my glorified bean bag that works as a slow cooker.  Just boil the food for a few minutes - pop the casserole in the bean bag and leave it all day!  Mine came from amazon.  Name may be back at the beginning of this thread.

edit!  How could I forget.....

Wonderbag. 6 Litre Small Polycotton Chipped Foam Portable Slow Cooker/Traditional Wonder Bag with Recipe Booklet, Green/Navy

Hay box technology for those old enough to remember easy to do DIY. 

Just reviving this thread to say that Morrison's (Southport for one) have the 1.5 litre slow cookers in store again.  Breville brand at £12 and own brand at £10.

Jill, you do a great job. 

We've used one for years, in the caravan and at home. They use a tiny amount of electricity, and are pretty fool proof. Cleaning is a doddle. Try a shin of beef casserole cooked all day, when you get home pop some spuds or canelini beans in, have a slurp of your vavourite tipple, when the tattles are ready, serve, yum. 

Thanks Jill, you must have read my mind, I was wondering about them only yesterday. Will have a look ....

If you don't find one at a Morrison's store, I've recently seen them in Lakeland Limited and Boundary Mill but a tad more expensive.

The original factory shop has a 1.5l swan slow cooker for £12 and their own budget range 1.4l one for £8

I have the second one.  It's light and works very well 

Thank you Jay, also again Jill, spoilt for choice now....

I got mine years ago in Asda £6, think it was up in Aberdeen, great thing to have in the van. Think I saw one in Argos once.

1 Litre capacity from Freemans.com  £20.
