Both types of mustard are made from mustard seeds. Yet, Dijon and yellow mustard sauces look and taste completely different.  Dijon mustard is a French mustard variation that is a lighter yellow and is also typically much more creamy. Dijon is made with spicy black and brown mustard seeds and has way less vinegar than yellow varieties. Dijon is best used to make spreads, glazes, and other creamy sauces. Then there is yellow mustard (which is also called American mustard) that has a very bright yellow color and super tangy. It’s made with white and yellow mustard seeds and is most commonly used as a condiment on sandwiches and burgers.
