To make balsamic reduction:
Place 1/2 cup of balsamic vinegar in a small saucepan and bring to a gentle boil. Continue cooking until the liquid is reduced by half, about 5-10 minutes. The vinegar should coat a spoon. It will thicken as it cools, and should be a good drizzling consistency once completely cooled. You may want to do this step ahead of time.
