When you're next at the store, you might notice both balsamic glaze and balsamic vinegar for sale. Balsamic glaze is balsamic vinegar that has been cooked down until it is thick and syrupy. It has a deep, rich flavor that pairs perfectly with bruschetta Caprese. Balsamic vinegar is a great cupboard staple to have on hand, but it is not the same as a balsamic glaze. It is much more tart and has a thinner consistency. So, if you have a choice, always use balsamic glaze when making this recipe.
