Here's a sort of vaguely julep-style concoction, created largely because I had a huge bundle of mint to use up. Also, Armagnac, which I love deeply.
1 oz Armagnac brandy
1 oz rye whiskey
1/2 oz passionfruit juice
1/4 oz mango shrub
1 dash aromatic bitters (Angostura in this case)
1 large bunch mint (about 20 leaves)
1 Demerara sugar cube
Muddle the mint and sugar in a mixing glass (add a small dash of water if needed). Add ice, shake briefly, and strain over fresh finely cracked ice. Garnish with a fresh bunch of mint.
