Made with just two simple ingredients, these fruit slushies are super delicious and refreshing. They're a great drink for warm days! Plan to freeze the apple slices, grapes, and watermelon cubes the day before (or at least in the morning) when you want to make these.
Blend, starting on low and working up to high. Use the stick that came with the blender (if you have one) to get the mixture going if needed.
Add a little more liquid if needed to make a thinnish icy mixture.
Serve right after making in a straw cup, an open cup with a straw, or a reusable pouch.
Notes
Use a juice in the same or a similar flavor as the frozen fruit you use, or use apple juice.
To make this without adding juice, you can do half frozen fruit and half fresh fruit, plus a little water if needed. This works best with watermelon and grapes, which have more liquid than other fruits. I would not advise trying to do that with fruit like apples.
