Combine all ingredients in a small/medium saucepan and simmer over low heat, whisking constantly or until thickened and no longer watery (6-9 min).
Keep in mind it thickens more as it cools.
Serve warm, at room temperature or chilled.
Refrigerate in an airtight container up to 2 weeks.
You can re-warm it slightly to make it more drizzle-able.
