Orgeat Syrup (pronounced ohr-zat) is a key ingredient in a number of tropical drinks.   So what is Orgeat Syrup you ask?  It is mostly almonds and sugar in a delicious syrupy form.  The Mai Tai is not a Mai Tai without orgeat syrup.  The problem is where do you buy the stuff?  I found it once at a local liquor shop.  I bought their entire stock of two bottles and they no longer carry it.  Fortunately, there is the internet. Trader Vic’s carries their own brand of orgeat syrup and it is priced at a reasonable $5.00. If you are planning on making a Mai Tai you should pick up a bottle.
