Pellegrino and Mint Lemonade

I worked in the garden much of the day today, then treated myself to some fresh, homemade minted lemonade.  So cooling and refreshing..

Pellegrino and Mint Lemonade

6 large lemons, halved around the equator
1/2 tray ice cubes (filtered water)
1 palmful fresh spearmint leaves
1-1/2 cups Pellegrino or other sparkling mineral water
sweetener of your choice

Use a exprimidor de lima (Mexican lemon squeezer) or other device to squeeze all of the juice into a blender, leaving the seeds and peel behind.   Add ice cubes, mint, mineral water and sweetener and pulse until the ice is crushed.  Taste and adjust for sweetness then serve immediately.
