In small saucepan, add vinegar, brown sugar and garlic powder(if using)
On low heat bring vinegar mixture to a simmer. Continue cooking until it is reduced by about 1/2 the amount or just starts to thicken. It will continue to thicken as it cools.
Transfer to small dish for drizzling
On a tooth pick, skewer in this order a grape tomato, a leaf of basil, a cube of mozzarella. Drizzle with balsamic reduction and enjoy!!
