Sour Orange Curry (kaeng som cha-om kai)
แกงส้มชะอมไข่

I always used to call it "orange curry" because of its colour and also because "som" means orange. It was only later that I found out that this word could also mean "sour" which is a good description of this curry. Most Thai curries use coconut milk. However, two notable ones don't. These are this sour curry and jungle curry. It is really a bit like a soup but it is often thick with vegetables. This 30 baht version was pretty plain, but you can also have ones with shrimp or fish. The sourness comes from the sour tamarind and lime juice. The main feature here is the "cha-om kai". This is a green vegetable called acacia which is then fried with eggs to make a kind of omlette. It is then cut into squares and added to the curry. I found this one a bit salty but I have tasted good ones in the past. Worth a try if you haven't tasted it before.
