Browsing through here and didn't see a mention of one of my favorites, thought I'd make a plug for all those rye lovers out there.
My Old Pal
3 parts rye
2 parts dry vermouth
1 part Campari
stir with ice, serve up with a lemon twist if so inspired
Lots of herbal, spicy, bitter savory notes going on, a nice break from the sweetness of a manhattan. Skol!
