Frosty cold! But super-delicious. And if you can’t finish it in one sitting you can always put it in the freezer and have it later.
Ingredients (for 4 large servings):
1 cup lime juice
1 cup raspberries
1 cup water
4 cups ice
2 tbsp sugar (optional)
1 cup of soda water
Put all ingredients except the soda water into a blender and blitz until slushy. Pour into glasses and top each with a little soda water.
Enjoy! And watch out for the brain freeze!
