Spicy Brown Mustard is made with brown mustard seeds, which are soaked in less vinegar than standard mustard. As a matter of fact, the combination of the hotter seeds and less acidity makes sure the nose-scorching heat is much more pronounced. Besides, Spicy brown mustard leaves the bran on the seeds, which don't fully break down when processed, giving the final sauce a coarser texture than yellow mustard. When it comes to their benefits, mustard seeds emerged from our food ranking system as an excellent source of selenium, a nutrient which has been shown to help reduce the severity of asthma, decrease some of the symptoms of rheumatoid arthritis, and help prevent cancer.
