Thanks for the tips. It appears I can get the Lemon Hart here in MI, but not the St. James - do you have another recommendation on a Martinique?
I'm almost out of grenadine and have to make up another batch, and just read the thread of Orgeat and think I can pull that off too. But I have a strong suspicion I won't be able to find any Falernum...
Rhum Clement is an excellent Martinique that is (in some parts of the US) easier to find than the St James. I like it a lot -- in fact, I'm sipping a Mai Tai made with Clement's VSOP right now.
Re falernum, if all else fails you can order the Fee Bros syrup online from quite a few vendors.
