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
orange bitters

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!
