I forgot to report back on my success today! Funnily enough, I too made a carrot soup, NotTooOld. But mine was spicy carrot and coriander. It was very very tasty - and very very spicy,
. Think I might put only half a teaspoon of chilli flakes in next time, not a whole one.
But what a wonderful gadget, so much easier than the old pan and blender method. I used the sauté function to part-cook and soften the chopped carrot and onion, then added the liquid and spices and left it to it. Twenty-one minutes later I had loads of gorgeous, thick soup. I texted DD and said would she like some fresh home-made soup for lunch and her reply was 'I'm on my way'
. So she and I had a very generous portion each and there were three more similar sized portions which went in the freezer (DH had had a meal at the golf club so he didn't have any).
I'm going to run out of takeaway containers (and freezer space) with all the soups I'll be making - or maybe I'll just give the excess away to DS and DD so I can keep trying out new recipes 
BTW, NotTooOld, re claiming commission, I was going to ask you if you worked for the company
