We served these for Shilo & Cheyenne's graduation party and they were a huge hit.
You can buy the syrup online direct from Torani, and if you order over $59, the shipping is free. World Market may have them also, you are just limited to the flavors they carry. We like to use the syrup for slushies and shaved ice all summer long.
In a 16oz glass or plastic cup:
Pour 1/4 c. flavored syrup (if you are mixing flavors, you want them to total 1/4 cup) in bottom, then
Fill glass or cup 3/4 full of ice
Add 2/3 cup sparkling mineral water (or club soda)
Pour in 2 to 4 Tbs. heavy cream
(Note: I use 2oz shot glasses/cups to measure. 1 (2oz) measure of syrup, any combination, 1 (2oz) measure of cream. Just makes all that measuring stuff easier.)
Stir with a straw.
And then enjoy another flavor.
Seriously, you may not be able to stop.
Lucky us, I slightly overbought for the party, so we have a stash that will last us (and our company) for a long, long time. Come see us and we'll serve you up.
