Brown Mustard Seeds
Brown mustard seeds possess a fiery flavor which rates in at 2 or 3 on a heat scale from 1 to 10. These seeds are commonly used to make whole grain and many coarse varieties of mustards. More and more, brown seeds have taken the place of black in Indian cooking.
The enzyme myrosine is what creates the pungent taste of mustard. This enzyme is activated by water. Thus, when cooked in oil, the taste of the seeds will remain subtle, and add a less pungent flavor to things such as curry pastes. Raw seeds are an important part of pickling and shrimp and crab boil blends. As with most seeds, dry-roasting them will bring out their aromatic and attractive flavor.
