http://thaifoodessentials.com/ For the lime extract. it is good. I can get the leaves but not easily.
I have heard bad things about the pandan extracts.
I have only found curry leaf oil sold for non-food uses - but don't see why "non-food' except that it has not been tested. Folks use curry leaf all the time - so why not?
this is a new one on me. I have never seen either of these extracts offered for culinary use in the US. Where do you obtain them?
Admittedly, Id be unlikely to use since I have a source for the fresh leaves. Also the asian pandan extracts ive tried have been much inferior to the fresh (frozen) leaves.
