The Tonga Tonga is a recipe from Jeffrey Morgenthaler, author of The Bar Book and bar manager of Clyde Common in Portland Oregon. The recipe itself is from a printer flyer with multiple recipes that came with Trader Tiki (now BG Reynolds) syrups. The flyer itself is undated, but I estimate it's from 2009-2010 or so (there are a few more cocktails from this flyer to come in time). Smith & Cross, grapefruit, lime, orgeat, bitters, and a float of ginger beer. The vessel is a Tiki Farm bucket produced for the Hula Hula in Seattle, Washington (currently moving locations within Seattle).
