@Endymion,
Some veggies really need something more than carrots for sweetness. Something to do with the chemistry of cooking.
mulling ... just read something about this
I made up a big pot of soup tonight. Started with a bit of oil, a couple of sliced onions, a couple of diced celery stalks, 3 or 4 chopped up bangers, 2 lamb chops, then a litre of chicken broth, 3 giant carrots sliced up, 2 enormous potatoes cut into shoestrings, herbs. Let everything cook for about an hour or so. Put a dollop of condensed tomato soup into a bowl for tomatoey creaminess, added about 2 cups of the veggie soup (left the meat in for Set to enjoy), stirred and enjoyed my soup.
I ran out of room for all the veggies I'd intended to put in - those carrots were huuuge. They'll (yellow beans/slivered brussel sprouts/fennel) go in tomorrow with more taters and a little more broth.
