I kind of made this up yesterday.
1 cup of balsamic vinegar
Bring to a boil then turn down to a simmer. Reduce the vinegar until thick and syrupy.
Grape Tomatoes (cut in half)
Basil Leaves (sliced in half lengthwise)
Spread the vinegar syrup in the bottom of a small serving dish.
Take a half of a basil leaf and fold in half and then half again. Skewer it onto a toothpick.
Then add one half of a tomato cut side down.
Then gently skewer the mozzarella pearl.
Place the skewer mozzarella side down onto your vinegar syrup.
Continue until your dish is full.
