1 oz Montanya Platino 1 oz Appleton VX 3/4 oz fresh lime juice 1/2 oz white grapefruit juice (fresh if available) 1/2 oz simple syrup 1/2 oz apricot brandy (Marie Brizard if available, otherwise use Bols) Dash of Fee’s Old Fashioned Aromatic Bitters (use caution, a few drops is all that's needed)
Shake with ice cubes and pour unstrained into a double old-fashioned glass or a tiki mug. I didn’t garnish it at the seminar, but a sprig of fresh mint would not be unwelcome.
