Blend the watermelon chunks, until smooth. Press watermelon juice through a strainer and catch all the juice in a bowl, and discard whatever doesn’t make it through the strainer.

In a medium sized sauce pan add the watermelon juice with the sugar. Bring mixture to a light simmer and stir until all the sugar is dissolved.

Pour into a heatproof glass pitcher. Refrigerate until cold.

In a large glass jar with a wide mouth for a ladle, add lemon slices around the bottom wall.

Dump in about 1/3 of the bag of pebble ice, you can add more later as needed.

Add the lemon juice, sparkling water and sweetened watermelon juice.

Add in a few slices of watermelon as a colorful garnish.

Serve with a big ladle making sure each glass gets a bunch of pebble ice. Garnish with a lemon slice or a small slice of watermelon…or both!
