Open, drain and rinse mozzarella pearls, set aside. I used pearls as I felt the mozzarella balls were slightly too big, but you decide.
Rinse blackberries and blueberries. Set aside on papertowel to ry.
Cut cucumber into ¾-1" slices and then cut into quarters. Set aside.
Rinse basil leaves and pat dry. Depending on the size of the leaves, cut into 1" strips width-wise.
Using your toothpicks, place your bites on starting with the mozzarella pearls, then a folded basil lear, followed by a blackberry, a piece of cucumber, another mozzarella pearl and finally a blueberry with the flower end facing out.
Place your skewers on your tray as you make them, My tray was long and for ease, I alternated the skewers between one side of the tray and the other, always with the part your guests will be grabbing facing out.
Refrigerate or serve right away, drizzling with balsamic glaze before serving or as an option for your guests.
You'll love that you can make these the day before the event!
