I love the humble white grapefruit and the wonderful nectar it produces. The bitterness/ sweetness balance is exactly what I appreciate in a citrus fruit. It works great in simple cocktails - both gin and tequila are natural companions with their inherent citrus notes.
If you're in possession of white grapefruit juice, either fresh squeezed (preferred, obviously) or from a bottle (I prefer Ocean Spray white grapefruit juice, which is surprisingly good for a bottled product and has no added sugar) and are wondering what to do with it, here are my two favorite recent grapefruit juice-based beverages for your consideration:
The first is a mash-up of a gin (the "english") greyhound and a pink gin. The second is essentially a Paloma made with grapefruit juice instead of soda (thus the "still")
They're both super easy to make. Try mixing up the ratios a bit for your optimal drink.
Pink English Greyhound
~2 oz. Gin (Beefeater (regular or 24))
~2 oz. white grapefruit juice.
2-3 dashes Angostura bitters
Fill a double old fashioned glass with ice cubes. Fill 1/3 to 1/2 with gin. Top with grapefruit juice. Stir. Float 2-3 dashes of Angostura bitters.
Still Paloma
~2 oz. blanco Tequila (El Jimador)
~2 oz. white grapefruit juice
1/4 lime
Fill a double old fashioned glass with ice cubes. Fill 1/3 to 1/2 with Tequila. Top with grapefruit juice. Squeeze lime into glass. Stir.
