Yup, it IS delicious!

I made this recipe of Bonnie's. I changed a couple of things due to availability, but it was very very yummy!
I used a Serrano chili instead of thai chilies. I did spoon a little garlic chili sauce over the top at the end for a little more spice.
I also have never heard of, nor could I find tamarind concentrate. But I found a web site that suggested I substitute some lime or lemon juice mixed with a touch of brown sugar. So I did.
