Sinigang Na Hipon - Filipino sour prawn soup

I reckon there is at least one sour soup recipe in every S E Asia country. I had Chinese hot and sour soup and Thai Tom Yum numerous times, tried the Vietnamese Cahn Chua not too long ago and last weekend I had the Filipino version of Prawn Sinigang which was very refreshing and tasty, not as herbal and fragrant as Thai or Vietnamese but is a keeper will try again with other combination.Sinigang
