I was not able to find sparkling grapefruit juice in my small town grocery store, so I substituted pineapple juice. Very tasty, but it really needs the sparkling grapefruit juice.

For those like myself, who may not know what that is or where to find it…I found it in the big city grocery store in the fruit juice isle. I bought the Izze brand, which comes in glass bottles, delicious!

Absolutely worth the effort…yum!
