This a family favorite on hot summer days when there's plenty of basil in the garden. I suppose you could make it using homemade lemonade. I've never been good at making that, so I use frozen :)
1 can frozen lemonade
1 generous handful of fresh basil leaves
1/2 cup boiling water for steeping basil leaves
borage flowers (optional)
In a pitcher, mix the lemonade according to the directions on the can.
Substitute some of the tap water for the 1/2 cup of "basil tea", discarding leaves.
Stir, then top off the pitcher with some sparkling water
(I use about a cup of lemon flavored mineral water)
Garnish with borage flowers
Yummy and thirst-quenching...try some!
