Sour Neon Doom

Chill a rocks glass or coupe by filling it with ice water and setting it aside to temper while you prepare the cocktail.

Measure and combine your base spirit — likely a bold whiskey or aged rum — along with any liqueur or modifier into a mixing glass.

Add a measured citrus sour element such as fresh lemon or lime juice, which provides the paradoxical sour character within this stirred preparation.

Add a sweetening agent such as simple syrup, demerara syrup, or a flavored syrup to balance the citrus acidity and complement the spirit.

Fill the mixing glass two-thirds full with large, clear ice cubes to ensure proper dilution and chilling without over-watering the drink.

Stir the cocktail steadily with a bar spoon for approximately 30 to 40 rotations until the exterior of the mixing glass feels well-chilled.

Discard the ice water from the chilled glass, then strain the cocktail over a large single ice cube or into the chilled coupe using a julep or Hawthorne strainer.

Garnish with a vivid, neon-colored citrus twist, edible glitter, or a fluorescent cocktail pick to honor the drink's striking 'Neon Doom' identity before serving immediately.
