A dark, tart syrup of reduced balsamic vinegar (an inexpensive brand is fine) is a sexy accent for oven-roasted sweet potato wedges. When making the drizzle, be sure to stand over the pan near the end: it can go from perfectly caramelized to horribly burned in just a few moments.
Make Ahead Tip: The balsamic drizzle (Step 3) will keep in the refrigerator for up to 4 days. Reheat in the microwave or on the stovetop, adding a little water if the syrup has thickened too much, before drizzling over the roasted sweet potatoes.
