In a small bowl, add the cornstarch and a few teaspoons of water until a thin, white liquid has formed. Set aside.
In a saucepan, add all of the ingredients – except the cornstarch slurry. Bring the sauce mixture to a boil over medium-low heat.
Add the cornstarch mix. Continue to heat for another minute or two until the sauce thickens. Stir it continuously – this will help the thickening.
Allow the sauce to cool completely before transferring to an airtight jar or container.

Notes
To store in the fridge: Store in an airtight container in the refrigerator for up to 3 weeks. To freeze: Once it's cooled, transfer the sauce into airtight containers (don't overfill as the liquid will expand upon freezing) and label with the date. For easy thawing, freeze in smaller portions. It'll keep in the freezer for up to 3 months. Thaw in the refrigerator before gently reheating when ready to use.Check the blog post for serving suggestions!
