Prep the rim: Mix 1 tablespoon sugar with 1/2 teaspoon ground cinnamon in a shallow dish.
Add a pinch of coarse salt if you want a sweet-salty balance. Run a lime wedge around the rim of your glass, then dip and twist it in the mixture to coat.
Chill the glass: Add a few ice cubes to the rimmed glass while you make the drink, or pop it in the freezer for a few minutes. A cold glass keeps the flavors crisp.
Shake the cocktail: In a shaker, combine tequila, orange liqueur, apple cider, and fresh lime juice.
Add maple syrup if you prefer a slightly sweeter sip. Fill the shaker with ice.
Shake hard: Shake for 15 seconds until the shaker is frosty. You’re chilling, diluting slightly, and blending the flavors.
Serve: Discard the ice from the glass.
Add fresh ice (big cubes if you have them), then strain the cocktail over the top.
Garnish: Add a thin apple slice, a lime wheel, or a cinnamon stick. Keep it simple; the rim is already doing a lot.
Taste and adjust: If it’s too tart, stir in a splash more cider or a touch more syrup. If it’s too sweet, add a squeeze of lime.
