A good tip for picking out a sweet watermelon is to get the one with the largest yellow bottom in the bin.
Clean and wash the watermelon.
With a knife, lop off the top.
Stand the watermelon in an appropriately sized bowl.
With a spoon scoop out some of the meat, place in a small bowl and set aside.
With the hand blender, slowly work your way down to the bottom. Be careful not to push too hard.
Push the blender up & down, side to side. Make sure to scrape the side of the watermelon as well.
Pour juice into a pitcher. Place reserved watermelon meat back into the cavity and blend again.
NOTE: After the first pour I figured out that cutting a V-notch on one side helps with pouring the juice into the pitcher more accurately.
Pour remaining juice into your pitcher. You'll end up with a cleaned out, hollowed out watermelon.
Et viola! Fresh watermelon juice. Flavour with lemon juice, ginger, & honey for a refreshing summer drink. Or combine with orange juice. Or just drink straight up with a couple of ice cubes. Enjoy!
