The longer you cook your dish, the more water that will evaporate and the thicker the liquid becomes—that means the flavors become more concentrated, too.

How much cornstarch is needed to thicken gravy? The ratio is an easy one to remember: Use 1 tablespoon of cornstarch per 1 cup of liquid for a perfect gluten-free gravy thickener every time.
