Another very simple, very straightforward drink with some interesting layers.
2 oz London Dry gin (a good strong one: Tanqueray, Beefeater, etc.)
2 oz mango-peppercorn-ginger syrup (not quite the standard procedure with this one; this is nothing more than 4 cups of mango juice, simmered with two tablespoons each of black peppercorns and roughly chopped ginger until it's reduced to about 2 1/2 cups, or roughly 2/3 of its original volume)
1/4 oz Luxardo
1/4 oz lime juice
Pour into a Collins glass over copious ice and stir.
This is aimed at the highball crowd - slightly aromatic, moderately sweet, and very approachable. Since we change our cocktail list every 3-4 months, I also expect that this will remain on our list until the early days of summer, and will definitely get more appealing as the weather gets warmer.
