Strawberry Hiru

Continuing on the "Fancy Girly Drink" theme with the Butterscotch Stallion...

2 oz gin (used North Shore No. 11)
0.5 oz dark rum (used Ron Zacapa Centenario)
0.5 oz simple syrup

2 strawberries
2 leaves shiso

2 dashes angostura bitters

muddle strawberries and shiso, add syrup, muddle some more. shake with the rest of the ingredients.
this could probably benefit from some citrus. it's a Japanese variation on Boont Strawberry Hill as is.
