Start by gathering all your ingredients. Ensure you have fresh lemon juice for the best flavor. If you prefer a sweeter drink, prepare simple syrup by dissolving equal parts sugar and water in a saucepan over medium heat, then let it cool.

2. Blend the Base

In your blender, combine the cranberry juice, vodka, lemonade, fresh lemon juice, and a handful of ice cubes. If you like your slush on the sweeter side, add the simple syrup to taste. Blend until smooth.

3. Add More Ice

To achieve the perfect slush consistency, add more ice cubes gradually while blending. Continue until you reach a thick, slushy texture. Taste and adjust the sweetness or tartness by adding more simple syrup or lemon juice as needed.

4. Serve and Garnish

Pour the slush into tall glasses. Garnish with fresh cranberries and lemon slices for a festive touch. Serve immediately and enjoy!
