Oh, I love soup too. Though Shan I made that recipe for corn chowder with sweet potatoes once, and as much as I like sweet potatoes, I didn't like them in this soup.
This month's edition of
Cook's Illustrated, a magazine I love, though it's quite over-the-top in its search for perfection of whatever they're making, is all soups! Veggies soups, meat soups, chili - I think there are about 20 soup recipes if you include the variations. It's a little pricey at $6.95, but fun reading along with great recipes. My SIL got me started on it, and everything I've made from the mag has been good, though not necessarily low-cal.
But like Zenor, my favorite soups are those that I just throw together from what I have on hand. Sometimes when they come out extra good I try to remember what I put in them.....
