Balsamic Vinegar Reduction
Cooking balsamic vinegar slowly, over low heat, will cause it to concentrate and thicken. It's delicious as a drizzle or glaze on many different foods.
The longer you cook it down, the thicker it will get, so depending on your time and preference, you’ll end up with about 1/2 to 1/4 of the amount of balsamic you begin with.
2 cups of balsamic vinegar (this will yield about ½ cup to 1 cup depending on the consistency you prefer)
Pour the balsamic vinegar in a small saucepan and cook over medium low heat until it has reduced by at least half (approximately 30 minutes) For an even thicker consistency, cook it until reduced to ½ cup (1/4 of the original amount)
Once the balsamic reduction reaches the consistency you prefer, remove it from the heat and let it cool.
