Begin by making a simple syrup that will sweeten your lemonade. In a small saucepan, combine equal parts granulated sugar and warm water (about 1 cup of each) over medium heat. Stir gently until the sugar fully dissolves, about 3-5 minutes. Once smooth and slightly thickened, let it cool.

While the syrup cools, roll fresh lemons on a countertop to maximize juice yield. Cut them in half and extract about 1 cup of lemon juice, ensuring it’s pulp-free.

In a large pitcher, mix the cooled simple syrup, freshly squeezed lemon juice, and 4 cups of filtered cold water. Stir well and adjust the sweetness as desired.

Carefully incorporate your choice of food coloring or activated charcoal into the pitcher. Start with a few drops or a teaspoon, stirring gently and adjusting to achieve the desired deep black hue.

Serve in clear glasses over ice, adding garnishes like lemon wheels or black sugar for a festive touch. Enjoy your refreshing Halloween potion!
