Don Beach's Planter's Punch

Seems like posting might be possible now, so here's my drink from last night! I wanted something refreshing, but still complex.

• 1oz Aged rum - Plantation 5 Year
• .5oz Jamaican rum - Wray and Nephew
• .5oz Dark rum - Plantation OFTD
• .5oz Lime juice
• .3oz Rich simple syrup
• .5 barspoons Falernum
• .5 barspoons Grenadine
• 2 dashes Angostura aromatic bitters

Blend with ice, serve in a Collins glass, and top with more ice. Garnish with two maraschino cherries, and a mint sprig (which I ran out of)
