I have used this product for a while now. I get it at my local health food store. It is vegan and has GM free ingredients as well as being gluten free. It is a concentrated stock similar to the one you can make in the EDC. As I had a jar of this open when I got my thermomix I have been using this in recipes which need the stock concentrate. When I have finished this jar I will make my own vegetable stock concentrate and see how it compares but it would be interesting to see if other people use it and what they think.
I know it is better to make your own so you know what precisely goes into it but i just thought I'd mention it especially with summer holidays etc coming up in Australia and if people take their TM caravanning etc it might be a good product to take along for convenience etc.
