Place the apple cider, granulated sugar and cinnamon sticks in a saucepan. Bring to a low boil, then maintain a low boil for 30 to 35 minutes until reduced to ¾ cup. Use immediately or refrigerate until using (stores up to 2 weeks refrigerated).
Cut a notch in a lime wedge, then run the lime around the rim of a glass. Dip the edge of the rim into a plate of salt or black colored sugar.
Place all ingredients in a cocktail shaker with 4 ice cubes and shake until cold.
Strain the margarita into the glass with the salted rim. Fill the glass with clear ice. If desired, garnish with a blood orange slice and Halloween cocktail picks.
Place 2 cups tequila, 1 cup apple cider syrup (make 1.5 or 2 times the recipe above!) and ½ cup lime juice in a pitcher. Add 3 handfuls ice and stir until cold. Pour into the prepared glasses.
