La Guildive is a delightful rum sour with the flavors of vanilla, baking spice, and homemade peach pie. It’s not too sweet, but the rich flavors give it the impression of being a dessert drink.
An aged rum with vanilla or caramel notes would go well here, like Angostura 1919 or Zaya 12. The pinch of cinnamon isn’t just a garnish; it’s a necessary ingredient that serves as a fragrant walkway leading to the first sip. Fresh-grated is best, of course!
