Make me a signature cocktail that includes honey and mango syrup. The cocktail should not be overly sweet and should also work as a mocktail.

Creating a balanced cocktail that uses honey and mango syrup can result in a delightful beverage full of rich and fruity flavors. If considering the options from the provided data, we can draw inspiration from the "Honey Bee" and "Mango Julep". Both cocktails possess unique characteristics that we can blend to create a new signature cocktail.

For a fusion that balances sweetness and lends itself well to being a mocktail, consider this idea:

Mango Honey Citrus Fizz

Begin with the base of honey syrup and mango syrup for a harmonious blend of creamy honey and tropical mango flavors. To ensure the sweetness doesn't overpower, introduce fresh lemon juice for a tart kick similar to that in "Honey Bee", which balances the sweetness naturally. Include a dash of soda water to add lightness and ensure it retains a refreshing quality—this draws from the fizz aspect in "Tango Mango". This ingredient also transforms the drink into a sparkling mocktail easily.

For the alcoholic version, white rum can be added for a smooth base, much like in many of the top cocktails listed. As a mocktail, the rum can be omitted entirely or substituted with a non-alcoholic spirit or additional soda water for dilution.

In presentation, serve in a cocktail or highball glass over ice. Garnish with a slice of lime or lemon for an attractive and aromatic finish. This combination achieves a cocktail/mocktail that is refreshing, fruit-forward, and elegantly balanced without being overly sweet.
