Spatulatta.com Watermelon Lemonade You'll need: Ice cubes Watermelon cut in 2 inch chunks Prepared lemonade A blender Fill your blender jar half-full of ice cubes. Put 8-10 chunks of watermelon into the jar. Pour in about 2 cups of lemonade. Put the top on the blender and hold tight. Press mix. It's going to be loud. When the ice and watermelon are all chopped up into a slushy mix put about the same amount of watermelon and a little more lemonade in. Put the lid on again and mix. Pour the slushy watermelon lemonade into pretty glasses. Be careful, because a big lump coming out of the blender could flip the glass over and make a mess. Cheers!
