I believe this Asian Chicken Noodle Soup from Eat Live Run's site is the closest approximation I've had since. It's really delicious and spicy, and basically the perfect thing to eat when it's so cold I can't get my toes to warm up. I'm not sure I can ever eat regular chicken soup again.
Ginger & garlic
This recipe gets two thumbs up from both me and my husband. It's such a perfect winter soup.
And if you aren't already a devoted fan of Eat Live Run, you must become one. I was just recently made aware of her site (thanks Lisa) and this is her second recipe I've tried, the first being the chicken tikka masala that I just about died over, I was so happy (In fairness she was trying someone else's recipe). She's also entertaining to read and has great photos.
