I love Thom com Ghai (I hope I didn't butcher that!)
Any way, it's the chicken & coconut soup.
I love making it especially when its chilly out, or when I've got a cold, because the curry just kind of opens up the sinuses and its so soothing.
When I make it at home, I don't make it with quite as much heat as normal, because my children would never eat it, and I add jasmine rice to it as well. But i make a huge pot, and it still doesn't last more then 2 days!
