Measure out 2 oz of tequila, 2 oz apple cider, 1 oz of pear juice, and squeeze ½ oz of orange juice.
If desired, mix 1 tablespoon cinnamon with 1 tablespoon sugar on a small plate.
Rim the edges of your glass with the remainder of the orange or with honey/agave, then dip in the cinnamon sugar.
Add all of the liquids into a cocktail shaker along with a handful of ice cubes.
Close the lid and shake aggressively for at least 30 seconds.
Strain and pour over ice or without ice into your rimmed glass.
If desired, top off the margarita with sparkling water, club soda, or even champagne.
Optionally garnish with apple slices, cinnamon sticks, rosemary, or any other fall-inspired ingredient!
Serve cold and enjoy!
