Tonight I tried Little Branch's Mercy, Mercy.
2 oz gin (I used Junipero)
1/2 oz Aperol
1/2 oz Lillet (I used Cocchi Americano as I've seen several variants of this drink using Cocchi).
A very nice Negroni variation. I might have to try it again with Lillet instead of Cocchi to see which version I like the best.
