1/3 Jalapeno or 1/2 Serrano pepper, thinly sliced
1/3 Persian cucumber, thinly sliced lengthwise
3 oz Grapefruit juice
Dash of simple syrup (more or less based on preference)
Garnish with a slice of pepper and a few slices of cucumber
The trick to this drink: muddle the pepper and cucumber before mixing.
Add vodka and strain.
Shake with ice in a cocktail shaker for at least 30 seconds. Drink should have ice chips in it.
