DC's signature drink, the Rickey, is "an airconditioner in a glass" as Columbia Room's Derek Brown puts it, and fiendishly simple. While the original uses bourbon, I prefer the gin version.

In a highball with ice, add in:
The juice of a key lime (and both shells, or the juice of 1/2 of a normal lime and a dash of simple syrup or an orange syrup)
2-3 oz of gin - and, for DC's own drink, use Green Hat, DC's own gin.
fill the glass with sparkling mineral water (pellegrino works well)

Equal parts:

• Gin (a fruit forward, botanical gin like Catoctin Creek is great for this)
• Aperol
• Lillet blanc

Shake or stir with ice, serve in a lowball glass with ice, garnish with an orange peel.

Via http://backyardbartender.blogspot.com/2010/10/el-sangre-de-fresa..., a recipe from Jeff Hollinger and Rob Schwartz, of the Absinthe Brasserie & Bar in San Francisco.

2 strawberries, hulled and quartered
4 to 5 basil leaves (thank you, backyard herb garden)
1/2 oz balsamic syrup (Recipe at link above, available in many gourmet grocery stores)
1 1/2 oz cachaça
1/4 oz Cointreau
1/4 oz fresh lime juice

Soda water

Muddle the strawberries, basil and balsamic syrup, add ice, then the liquors and lime juice, shake, strain into a highball, and top with soda

Equal parts:

• gin
• Campari
• sweet vermouth

Mix with ice in a lowball.

If you have genever, this is one of the few cocktails where you can sub it in directly for gin, though TheGinisIN recommends "In fact, if you up the Genever and Vermouth in the 1:1:1 ratio to a 2:2:1 you come up with a cocktail that is the sophisticated brother of the Manhattan. The Campari brings a lot of the qualities that the bitters in a Manhattan bring to the table."
