Orgeat syrup is a sweet syrup made from almonds, sugar and rose water or orange flower water.

It's a hot-weather gin drink with lemon juice, pineapple juice and orgeat syrup, an old-time favorite made from barley and flavored with almonds and orange flowers.

Historically, almond syrup was an emulsion of sweet and bitter almonds, usually made with barley syrup (orgeat syrup) or in a syrup of orange flower water and sugar.

Special flavoring and coloring agents include liqueurs (such as Grand Marnier or Chartreuse), Cordials, and non-alcoholic flavored syrups (such as Grenadine or Orgeat syrup).

The building, located on the north-western side of the piazza, was a popular meeting place for the Milanese people for over 400 years; it housed several shops that sold such drinks as the turbolin (boiled and filtered coffee), chocolate, barbajada, orgeat syrup, and more.

The authors have also come up with their own tiki-inspired originals, like Hell in the Pacific (151-proof Demerara rum, lime juice, maraschino liqueur and grenadine), and the Waikikian (light Puerto Rican Rum, dark Jamaican rum, lemon juice, curacao and orgeat syrup).
