This drink first appeared in our feature on The Bamboo Cocktail.

60ml Dry sherry (ideally a fino or manzanilla)
20ml Dry vermouth
2ds Orange bitters
1ds Aromatic bitters (optional)

Stir over ice, strain into a chilled cocktail glass, and express the oils from a lemon twist across the surface and garnish. A skewered olive is a nice touch if the mood strikes, or better yet a few toasted almonds on the side.
