Combine hot water and brown sugar and stir until sugar has dissolved. Add remaining ingredients and let the sauce sit for 1-2 minutes, stirring a few times.
Slowly add the mixture to pulled pork. Use tongs to gently fold meat together with the sauce. Use enough sauce to create a nice coating and little moisture. Some opt for a saucier pulled pork, while others like it less pronounced. The choice is yours.
Make sauce ahead of time and store in air tight container in the refrigerator for up to 1 week. Bring sauce to room temperature before using.
