In a small pot, combine sugar and 3/4 cup of water. Bring to a gentle boil over medium heat, stirring occasionally until sugar dissolves. Simmer for 3-4 minutes. Stir in black gel food coloring until desired hue is achieved. Allow syrup to cool.

In a large pitcher, combine cooled sugar syrup with 1 1/2 cups of freshly squeezed lemon juice. Add 4 cups of cold water and stir well.

Fill tall glasses with ice cubes. Pour the Bewitching Black Lemonade over ice and garnish with a lemon slice or Halloween decoration if desired.

Stir the lemonade before serving to ensure ingredients are mixed evenly.
