Step by step

1. Slice your watermelons in half so you have two end pieces.

2. Fit your KitchenAid® 400 Blender base with the Citrus Press attachment.

3. Turn to speed 1 and, with two hands, hold the watermelon half and gently press it onto the reamer.

4. Juice the watermelons until you have 24 ounces (709 ml) of watermelon juice.

5. Pour the juice into ice cube trays, and freeze until solid.

6. Fit the blender with the blender jar and add watermelon juice cubes and add remaining ingredients. Turn to speed 5 and blend until smooth, about 15-20 seconds.

7. Divide slushie between 4 glasses and serve immediately.

8. Because of the width of the watermelon rind, use your palm to place pressure on one side of the watermelon rind while juicing. Also, if there’s watermelon meat left at the top inside the rind after juicing, trim off the bottom 1” of the rind and then place it back on the reamer to juice.
