1 3⁄4 oz Rye (cacao-infused; see note)
3⁄4 oz Oloroso sherry
1⁄2 oz Meyer lemon juice
1 Cherry (as garnish)
Stir, strain, up, garnish.
Lepkowski infuses her rye with cacao nibs, black pepper, ginger, and other botanicals; recipe at link. Alternatively, a dash of chocolate bitters in combination with the oloroso sherry produces a dry chocolate-y effect.
