Philly is heating up, and so is this drink. Mix up your repertoire with something spicy!
Grapefruit
Salt
Ice
2 oz Grapefruit juice
2 oz Tequila
Jalapeño
Citrus or lemon-lime soda
Rub the rim of your glass with a grapefruit wedge and dip in salt to coat. Fill with ice.
Fill a cocktail shaker halfway with ice. [Ed. note: If you don't have one, substitute two glasses, rims held tightly together. Or up your bar-game and buy one.] Add grapefruit juice, tequila, and jalapeño—start with one slice, add more if you can take it. Cover and shake vigorously for about 30 seconds. Strain into glass and add soda.

Garnish with grapefruit or jalapeño if you're tryna get fancy.
