Add the fruit, ice, juice, water and honey (if using) to a high speed blender. Blend on high until smooth, for about 8-10 seconds. You want the slushie to be liquid, but still have the icey mouth feel, so I suggest trying a spoonful at the 8-10 second mark, and blending further to your desired texture if needed.
Use a spoon to spoon the slushie into a glass. Serve with a thick straw!

Notes
Don't over-blend! Blending the slushie for too long will eventually turn it into more of a smoothie texture. Lean towards the side of blending less, and then just blend more as needed.
Add more liquid if needed. If your blender is a bit on the weaker side, it may need an extra splash of liquid to blend easier.
Cut the fruit juice with water or sparkling water for less sugar. If you want it to cut down the sugar a bit, you can use less juice and water instead.
