The other night I wanted to make a whiskey cocktail but didn't feel like juicing any fruit. So I went for the fruitiest thing in my cabinet, Cointreau. I really expected this to be a starting point, but I've made it three times since and it is really pretty good:

Slade Sunset (named for the 'town' in the Red River Gorge, KY area)

1.5 floz bourbon (I used OGD BIB)
0.5 floz Cointreau
4 good shakes of Peychaud's bitters

Shake with ice and strain. It's orangy, with more than a hint of gentian. The color is delightful.
