The mustard helps the oil to blend with the other ingredients and STAY blended. If you don't put any mustard in it, the oil will separate fairly quickly.
1. Place the root beer in a pot over high heat. Reduce to a light syrupy consistency, turning the heat a little lower as it begins to heat up.
Set aside to cool.
2. Mix the dry ingredients together, then add the, cooled, root beer reduction, the oil, and the mustard and mix well with a whisk. Add additional root beer is the mixture is too thick.
