Involving
Shallots, coriander, garlic, ginger, green chilli, bit of sugar, fish sauce or shrimp paste (or both?). No lemongrass in the actual paste, you bash the lemongrass and let it seep in the curry when you cook that.
There might have been basil in it, meant to be chinese basil but I used to use basil.
It was with a prawn curry recipe apparently
I used to cook this regularly but havent for years and want to get it exactly right.
Cant remember the exact details
