British-style “French mustard” would also be classed as a “moutarde douce” – a term used for certain sweeter, milder mustards in France. Dijon is a dark yellow, with a milder taste than English mustard, but still with more bite and a more classic mustard taste than the sweetish, savoury, “French mustard”.
Dijon mustard is a vital ingredient in just about every sandwich. It’s perfect with eggs or potatoes (i.e.: devilled eggs, egg salad, mashed potato, potato salad), and provides the right finishing note for simple cheese dishes like mac and cheese or a grilled cheese sandwich.
Mustard contains antioxidants and other beneficial plant compounds thought to help protect your body against damage and disease. For instance, it’s a great source of glucosinolates, a group of sulfur-containing compounds found in all cruciferous vegetables, including broccoli, cabbage, Brussels sprouts, and mustard.
