Tonight I made a "Navy Grog" according to the Trader Vic specification as detailed in the book. Interestingly the Don the Beachcomber specs are also listed. What was crazy is how balanced it was. I don't mean to put out the whole recipe, but most of the book can be searched for on google books.
.75 Lime / .75 grapefruit
.25 rich demerara / .25 allspice dram
1 oz each of three different rums
And these are the rums I used:
1 oz Plantation 3 star
1 oz Smith and Cross
1 oz Bacardi Extra Anejo
1.5 oz of citrus balanced by .25 oz of syrup and .25 of liqueur that I don't think of as particularly sweet. And it's not like any of the rums are particularly sweet, either.
Funny thing, I had hesitated to make it since I didn't have the ice cone mold, but it's not even used in the Trader Vic version, so there that.
