I've been making carrot soup, in fact I've just had a bowl
I just use, 1-2 onions, and maybe a pound of carrots. Chop & sweat down, then add salt, cumin and ground corriander. Cook for a little while then add chicken stock, about a pint & a half & some skimmed milk.
Bring to boil & simmer for 20 mins or so, then bliz with hand blender. Add some chopped corriander if you have it. and adjust thickness with milk/water.
It's sooooo nice and superfree too
YOu can add a chilli at the sweating stage if you want it more spicy.
