Step 1

Add all ingredients to a saucepan on medium heat and bring to a simmer, whisking regularly to mix well.

Step 2

When it reaches a simmer, reduce the heat and let it simmer for 10 minutes, whisking regularly, to let the sauce reduce and thicken. If you want a thicker sauce, you can let it simmer for longer.

Step 3

Remove it from the heat and allow it to cool completely.

Step 4

Transfer the sauce to an airtight container or jar and refrigerate.
