My daughter introduced us to Mojito's at the Samba Room in Dallas. My wife and I found it to be our favorite warm weather cocktail (about 9 months a year in south Texas) and soon perfected our own favorite recipe for home use.
So far so good. The problem ensues when we order them at bars/restaurants, about 50-75% range from great to drinkable with the balance being an ungodly concoction not fit for human consumption. Our personal worst involved a combination of Creme de Menthe ("sorry, we have no mint") and Dr Pepper. Recently I had a bartender tell me he uses bottled lime juice and adds Vermouth!
There seems to be little consistency when it comes to this cocktail, resulting in my usually ordering some less pleasing alternative.
