Slightly reminiscent of the Martinez, the Tomcat features a sweeter style of gin called Old Tom. You can think of this style as the missing link between Genever and London Dry gin. The cocktail itself is simple to make, and you have a few options for the brand of gin, including San Francisco's Anchor Distilling and Hayman's Old Tom. Meow.
2 oz Old Tom gin
.5 oz Cardamaro**
.5 oz Carpano Antica sweet vermouth
one dash of orange bitters
Stir until chilled and diluted (about 30 seconds or so), and strain into a chilled, stemmed cocktail glass. Garnish with an orange twist.
**Cardamaro is an Italian wine based amaro that's made with cardoon, a relative of the artichoke. The name can be slightly misleading since many may be expecting a cardamom spirit on first glancing at the label. It's both bitter and sweet, and lower in proof than many distillate-based amari. You can find it in many specialty liquor stores.
