This is the name my friend and I have given to the cocktail we drank on Royal Wedding Day with cucumber sandwiches in my new house. We also drank it on a hen weekend recently along with enough wine and vodka to fill a small lake. You need:
Prosecco or champagne
I grated some cucumber into the glass underneath the ice the first time but you don't need it. Try it! Perfect for sunny days and bbqs with friends.
