  • Over medium high heat, bring the liquid just to a boil and then drop the heat to a simmer. To prevent scorching, burning, or a yucky skin, stir continuously for the next 10-15 minutes or until the liquid has thickened and reduced by about a third.
  • Use a fine mesh strainer to remove the onion, cloves, and bay leaves from the sauce. Pour the liquid back into the saucepan and set it over medium heat.
