Thai Green Curry Halibut

Why I Love This Recipe
Another one from Karen Barnaby's 'Halibut - The Cookbook'. Just a great book for halibut recipes as you can tell. This one she got from Susan Mendelson's 'Mama Now Cooks Like This.
Intro to this says she learned to make it in Phuket, Thailand in a cooking class.
Ingredients You'll Need
4 cups - coconut milk, divided
1 1/2 oz - Thai green curry paste
6 - small Thai eggplants, cubed (substitute Japanese)
2 1/4 tbsp - fish sauce
2 tsp - palm sugar
2 - kaffir lime leaves (I buy them fresh and then freeze them in a small baggy)
3 lb - halibut, cut into chunks
1 tbsp - Thai basil leaves, chopped (substitute sweet basil)
Directions
Combine one cup of the coconut milk and the green curry paste.
Cook down the mixture until the milk starts to separate.
Add the remaining coconut milk, eggplants, fish sauce, palm sugar, and lime leaves.
Cook until thickened.
Add the halibut and basil and cook for 3 - 5 minutes more.
Serve with fragrant jasmine rice.
