Add apple cider and lime juice. Shake gently for 10 seconds.
Strain into a glass with fresh ice.
Top with ginger beer and gently stir.
Garnish with apple slices and cinnamon stick. Add ginger slice if desired.
Notes
Use unfiltered cider for richer flavor. Adjust ginger beer for sweetness. For an adult version, add a splash of spiced rum. Serve immediately to keep the fizz fresh.
