You just need four ingredients to make Red Wine Slushies in your blender! Wow your guests with these delicious, stunnning and refreshing frozen drinks. Note, you'll need to freeze the wine cubes for four hours.
Fill two ice cube trays with red wine and freeze them for four hours. You can make eight slushies right away, or make two at a time (see notes) and save the remaining frozen wine cubes for another time.
To make eight slushies, you'll need to make the recipe in two parts, since everything won't fit in the blender at once. Start with two cups of cold water in a measuring cup. Whisk in six tablespoons of sugar until completely dissolved. (Don't heat it, because you need the mixture to be cold.)
Add 12 frozen wine cubes to your blender. Pour the sugar/water mixture into the blender. Add two cups of plain ice cubes. Blend briefly, just until slushy. Pour the slushies into four glasses and repeat the process to make four more. (You will have four extra wine cubes that you can throw into the blender with this batch, or save for later use.)
Store any leftover slushies in a plastic or glass container in the freezer. Thaw them at room temperature until slushy.
Notes
Be careful not to blend the slushies too long. You want to make sure there's visible crushed ice.
To make two slushies, place six frozen wine cubes in the blender. In a measuring cup, whisk one cup of cold water with three tablespoons of sugar until it's dissolved completely. Pour the water mixture into the blender, add one cup of plain ice cubes and blend until slushy.
