Prepare the Jalapeño: Start by slicing the jalapeño. If you prefer less heat, remove the seeds and membrane before slicing. Adjust the amount according to your spice tolerance.
Mix Ingredients: In a shaker, combine the gin, fresh grapefruit juice, simple syrup, lemon juice, and jalapeño slices. If you're using a muddler, lightly muddle the jalapeños to release their flavors, but don’t overdo it unless you want a spicier kick!
Shake It Up: Fill the shaker with ice, then shake vigorously for about 15-20 seconds to chill and mix the ingredients well.
Strain: Using a strainer, pour the mixture into a highball or Collins glass filled with ice.
Top It Off: Fill the glass with club soda to your liking, giving it a gentle stir to combine.
Garnish and Serve: Garnish with a slice of grapefruit and a jalapeño slice. Enjoy your refreshing Spicy Grapefruit Collins!
Variations
Spicy Grapefruit Fizz: Substitute gin with tequila for a Mexican twist.
Herbal Version: Add a few fresh mint leaves or basil for a refreshing herbal note.
Fruit-Forward: Muddle some fresh strawberries or raspberries with the jalapeño for a fruity kick.
