Gin Mare

• 1 ½ ounces gin mare
• 1 ounce fresh lime juice
• ¾ ounce fresh grapefruit juice
• ¾ ounce manzanilla sherry syrup
• 1 pinch salt
• 2 dashes orange bitters
• 2 dashes celery bitters
• Seltzer
• Grapefruit slice and sprig of parsley, for garnish

Make the manzanilla syrup: combine equal parts manzanilla sherry and sugar. Bring to a boil and simmer for 30 minutes. Let cool. (Note: use inexpensive manzanilla sherry, if you can find it.)

In a cocktail shaker filled with ice, combine the gin, lime juice, grapefruit juice, manzanilla syrup, salt, and bitters. Shake well to combine and strain into a highball glass filled with ice. Top with seltzer and garnish with the grapefruit slice and parsley.
