Step 1

For the Rub: Whisk all rub ingredients together to combine. Use your fingertips to break up any large clumps of brown sugar. For better flavor, before combining, toast ground mustard, black pepper, and coriander in a dry skillet over medium heat until fragrant. Store rub in a sealed container at room temperature for several months. (It will lose flavor over time, but it will not go bad.)

Step 2

For the Sauce: Combine all sauce ingredients in a small saucepan over medium-low heat. Whisk together and simmer until reduced to a glaze consistency, about 15 minutes (sauce should reduce by about one-third). Adjust flavor with more molasses, vinegar, or hot sauce to taste. Cooled barbecue sauce can be stored in a sealed container in the refrigerator for several months.
