Barry.....I've never come across curry leaves here or vanilla for that matter.
Pandan doesn't taste like vanilla at all. The comparison comes from the fact that many Thai desserts and sweets are pandan flavored just as many are vanilla flavored back in the west.
Like I said before, pandan chicken (chicken pieces wrapped in pandan leaves and then fried) is apparently very popular in Thai restaurants overseas. I have never seen it on a menu here though, but my wife has made it several times.
The hardest thing of all is trying to convince the average Thai that the leaves must be left to wilt first. If you go into any Mom and Pop shop you'll see buns or whatever with a green filling. This is pandan flavored filling but made from artificial pandan flavoring. Real pandan won't color your food (unless you grind it into a paste) at all, even if you use fresh green leaves. By the way, the leaves aren't eaten....(unless you grind it into a paste)
If you want to try some, just look for one of the places selling flowers next to the road......you know, those yellow flower arrangements that can be attached to the front of your car and etc. The flowers are usually accompanied by a bunch of long green leaves which are pointed, and these are the leaves you want. Otherwise, if you want I can let you have some leaves or whatever the next time I see you.
Just keep the leaves and allow them to dry out for a couple of days. The smell of the dried leaves is not exactly the sort of aroma they impart when used in cooking. I've also read that some restaurants use this to give cheap rice some fragrance and then charge for fragrant rice.

Actually, my wife nearly always adds a few leaves to the rice. Bless her - they're green leaves and they don't do anything at all.
Dannie Boy - sometimes when you buy the flower arrangements the pandan leaves will still be joined to each other at the base, in which case you can put them in some water until they get roots. Otherwise, just ask the seller to get you some shoots. Once they get going, you can just separate the small offshoots and replant.
