I agree about the soup maker. I used to use a pan, and thought nothing could be simpler, but the machine is fantastic. DD got me a Morphy Richards, not the one currently on offer, from groupon. I have to chop the veg, but into large chunks, which the maker whizzes to the consistency needed. There will be extra carb and sugar in the stock you choose, but will be a tiny amount only (I use Knorr stock pots).
Incidentally, NanKate, DD found a 50% deal on afternoon teas for my birthday on the Groupon site, the venue is a secret!. There are some fantastic deals on goods and events, she uses it all the time.
