Homemade Lemonade with Ginger and Maple Syrup

I was at Balzac's (the coffee shop) the other day and saw on their menu lemonade with ginger and maple syrup.  It was a bit expensive so I didn't end up getting it, but went home and made it that afternoon.  It was DELICIOUS!  So refreshing and tasty.  Yum.  Please make it - it is worth the trouble.

Heat in a pot for 15 minutes:

3 lemons worth of lemon juice
1/3 cup maple syrup
grated ginger (as much as you like)
4 cups water

Remove from stove and add in 10 ice cubes.  When cool, put into fridge.

That's it!  Enjoy!
