The Orange Blossom martini is a simple and elegant version of the Screwdriver highball. The name also derived  from the practice of adding fresh orange juice to the bathtub gin during the years of Prohibition in order to conceal its awful taste. Make the Orange Blossom with a good quality gin, which needs no such concealment. This lovely libation is really easy to make, and  combines equal parts of gin and orange juice with a dash of orange liqueur. A delightfully refreshing cocktail.
