Thai soups are good if you're looking for hot, sour soups. If you want another variety, you should try Sinigang. It's a type of Filipino soup that has a tamarind base. That's what makes it sour. It's really good.
Just google Sinigang, I'm sure you can find the recipe that way.
It's a soup I eat when I'm sick. It really sooths my throat. It's yummy.
