The San Francisco is a classic cocktail that was created in the 1930s and was first published in the Café Royal Cocktail Book by William J. Tarling and the United Kingdom Bartenders Guild. It's traditionally made with equal-parts sloe gin, dry vermouth, and sweet vermouth, and it's paired with a few dashes of both aromatic and orange bitters for extra flavor and balance.
Add sloe gin, dry vermouth, sweet vermouth, aromatic bitters, and orange bitters to a shaker.
Fill shaker with cubed ice.
Shake for 10-20 seconds.
Using a Hawthorne and fine mesh trainer, strain into a Nick & Nora glass.
Garnish with cherry.
